Issue 10 of Green Chemistry is now available to read online.
The front cover this month (pictured left) features work by Nicholas Gathergood and Stephen Connon and co-workers from the Czech Republic, Spain and Ireland. In their series of three back-to-back papers, they report how consideration of green chemistry metrics in tandem with performance studies can lead to prioritising safer ionic liquid solvents and imidazolium derived catalysts. Metrics determined include – antimicrobial toxicity, biodegradation, atom economy and length of catalyst synthesis. Performance of the imidazolium derived catalysts was greatly enhanced by incorporation of either esters or amides into the heterocyclic core, leading to low catalyst loadings. A Traffic Signal Light classification system was used to conveniently compare ionic liquid solvents and imidazolium derived catalysts metrics.
