A solvent-free catalytic protocol for the Achmatowicz rearrangement

Graphical abstract: A solvent-free catalytic protocol for the Achmatowicz rearrangement


Reported here is the development of an environmentally friendly catalytic (KBr/oxone) and solvent-free protocol for the Achmatowicz rearrangement (AchR). Different from all previous methods is that the use of chromatographic alumina (Al2O3) allows AchR to proceed smoothly in the absence of any organic solvent and therefore considerably facilitates the subsequent workup and purification with minimal environmental impacts. Importantly, this protocol allows for scaling up (from milligram to gram), recycling of the Al2O3, and integrating with other reactions in a one-pot sequential manner.

A call to (green) arms: a rallying cry for green chemistry and engineering for CO2 capture, utilisation and storage

A call to (green) arms: a rallying cry for green chemistry and engineering for CO2 capture, utilisation and storage

 Author affiliations


Chemists, engineers, scientists, lend us your ears… Carbon capture, utilisation, and storage (CCUS) is among the largest challenges on the horizon and we need your help. In this perspective, we focus on identifying the critical research needs to make CCUS a reality, with an emphasis on how the principles of green chemistry (GC) and green engineering can be used to help address this challenge. We identify areas where GC principles can readily improve the energy or atom efficiency of processes or reduce the environmental impact. Conversely, we also identify dilemmas where the research needs may be at odds with GC principles, and present potential paths forward to minimise the environmental impacts of chemicals and processes needed for CCUS. We also walk a different path from conventional perspectives in that we postulate and introduce potential innovative research directions and concepts (some not yet experimentally validated) in order to foster innovation, or at least stoke conversation and question why certain approaches have not yet been attempted. With elements of historical context, technological innovation, critical thinking, and some humour, we issue a call to arms and hope you may join us in this fight.

The Green ChemisTREE: 20 years after taking root with the 12 principles

Author affiliations


The field of Green Chemistry has seen many scientific discoveries and inventions during the 20 years since the 12 Principles were first published. Inspired by tree diagrams that illustrate diversity of products stemming from raw materials, we present here the Green ChemisTREE as a showcase for the diversity of research and achievements stemming from Green Chemistry. Each branch of the Green ChemisTREE represents one of the 12 Principles, and the leaves represent areas of inquiry and development relevant to that Principle (branch). As such, in this ‘meta-review’, we aim to describe the history and current status of the field of Green Chemistry: by exploring activity within each Principle, by summarizing the benefits of Green Chemistry through robust examples, by discussing tools and metrics available to measure progress towards Green Chemistry, and by outlining knowledge gaps, opportunities, and future challenges for the field.

Diet rich in tomatoes and apples may help restore lung damage caused by smoking — Med-Chemist

New Drug Approvals

A study from the Johns Hopkins Bloomberg School of Public Health found the natural decline in lung function over a 10-year period was slower among former smokers with a diet high in tomatoes and fruits, especially apples, suggesting certain components in these foods might help restore lung damage caused by smoking.The researchers found that adults…

Dimethyl carbonate: a versatile reagent for a sustainable valorization of renewables

Dimethyl carbonate: a versatile reagent for a sustainable valorization of renewables

 Author affiliations

Giulia Fiorani

Postdoctoral Research Fellow presso University of Oxford
Dr. Fiorani earned her PhD in Chemical Sciences from the University of Rome “Tor Vergata” (2010) on synthesis and applications of ionic liquids. After several post-doctoral experiences (University of Padua, Italy 2010-2012, Ca’ Foscari University of Venice 2012-2013), Giulia was awarded a Marie Curie Intra-European Fellow in 2014 at ICIQ (Institute of Chemical Research of Catalonia, Tarragona, Spain) working under the supervision of Prof. Arjan W. Kleij  on the preparation of cyclic organic carbonates from CO2 and terpene based oxiranes. Giulia joined the Williams group in 2016 and is working on renewable based polymers.


Dimethyl carbonate (DMC) is an environmentally sustainable compound which can be used efficiently for the upgrading of several promising renewables including glycerol, triglycerides, fatty acids, polysaccharides, sugar-derived platform molecules and lignin-based phenolic compounds. This review showcases a thorough overview of the main reactions where DMC acts as a methylating and/or methoxycarbonylating agent for the transformation of small bio-based molecules as well as for the synthesis of biopolymers. All processes exemplify genuine green archetypes since they couple innocuous reactants of renewable origin with non-toxic DMC. Each section of the review provides a detailed overview on reaction conditions and scope of the investigated reactions, and discusses the rationale behind the choice of catalyst(s) and the proposed mechanisms. Criticism and comments have been put forward on the pros and cons of the described methods and their perspectives, as well as on those studies which still require follow-ups and more in-depth analyses.

A roadmap towards green packaging: the current status and future outlook for polyesters in the packaging industry

DOI: 10.1039/C7GC02521A, Tutorial Review
M. Rabnawaz, I. Wyman, R. Auras, S. Cheng
Approximately 99% of the plastics used in the packaging industry today are petroleum-based. However, the adoption of biobased plastics could help to greatly reduce the environmental footprint of packaging materials and help to conserve our non-renewable petroleum resources. This tutorial review provides an overview of renewable polyesters and their potential packaging materials.

Approximately 99% of the plastics produced today are petroleum-based, and the packaging industry alone consumes over 38% of these plastics. In this review, we argue that renewable polyesters can provide a key milestone as renewable plastics in the route toward green packaging. This review describes different classes of polyesters with particular regard to their potential use as packaging materials. Some of the families of polyesters discussed include poly(ethylene terephthalate) and its renewable analogs, poly(lactic acid), poly(hydroxyalkanoates), and poly(epoxy anhydrides). The synthesis of polyesters is discussed from a green chemistry perspective. A structure–property correlation among the various polyesters is also discussed. The challenges that currently hinder the widespread adoption of polyesters as leading packaging materials are reviewed. The environmental footprint and end of life scenario of polyesters are discussed. Finally, future research directions are summarized as a possible roadmap towards the widespread adoption of renewable polyesters as sustainable packaging materials.

Research Interests

I have published more than 20 research articles in the field of polymer and materials sciences. Our initial endeavors can be divided into three broad categories:

  1. Polymer synthesis from renewable feedstocks.
  2. Design and preparation of smart materials.
  3. Polymer composites.

Our projects are highly applied, and we expect close collaboration with world-leading industries. These partnerships will offer unique training and career opportunities for the group members.
