En route to full implementation: driving the green chemistry agenda in the pharmaceutical industry
Focus on the outlook for a green future in the pharmaceutical industry – close-up of historical drivers, blockers, challenges, and changes.
Green chemistry and the ocean-based biorefinery
Competition for land use could be minimized if marine sourced feedstocks were used for chemicals and materials production rather than crops grown on fertile land.
Direct aerobic oxidation of 2-benzylpyridines in a gas–liquid continuous-flow regime using propylene carbonate as a solvent
The use of continuous flow technology enables a fast and efficient oxidation of 2-benzylpyridines in propylene carbonate using compressed air as an oxidant.
Ruthenium(II)-catalyzed selective monoarylation in water and sequential functionalisations of C–H bonds
The selective monoarylation of arene C–H bonds, with arylchlorides and heteroarylhalides, is efficiently performed using a RuCl2(PPh3)(p-cymene) catalyst operating in water and it is followed by a different (hetero)arylation with a Ru(OAc)2(p-cymene) catalyst in water to produce mixed bifunctional derivatives.

Reactions of p-coumaryl alcohol model compounds with dimethyl carbonate. Towards the upgrading of lignin building blocks
Models of lignin building blocks can be converted catalytically into different products with tuneable selectivity by using dimethylcarbonate.
Cycloaddition of CO2 to epoxides catalyzed by imidazolium-based polymeric ionic liquids
A cross-linked ionic polymer derived from a styrene-functionalized imidazolium ionic liquid displays high efficiency and reusability as a heterogeneous catalyst for the cycloaddition of CO2 to epoxides.
Recycling Pd colloidal catalysts using polymeric phosphine ligands and polyethylene as a solvent
Polyisobutylene (PIB)-bound azo dyes were prepared from aryl amine terminated polyisobutylene oligomers and used to form palladacycle precatalysts that can be used for catalytic carbon–carbon cross coupling reactions.
Facile insertion of CO2 into metal–phenoxide bonds
The insertion of CO2 into cobalt– and zinc–phenoxide bonds was found to occur rapidly suggesting it to be a facile key-step in the copolymerisation of carbon dioxide with epoxides.
Production of polyetheretherketone in ionic liquid media
Polyetheretherketones were synthesised in the ionic liquid 1-butyl-3-methylimidazolium bis{(trifluoromethyl)sulfonyl}amide and recovered with high separation efficiency.
Paper
Methylation using dimethylcarbonate catalysed by ionic liquids under continuous flow conditions
Efficient, continuous flow methylation was effected with dimethylcarbonate using a basic ionic liquid as catalyst.
A clean enzymatic process for producing flavour esters by direct esterification in switchable ionic liquid /solid phases
By using an iterative cooling/centrifugation protocol, a clean biocatalytic approach for producing flavour esters in switchable ionic liquid/solid phases has been developed.
Ruthenium nanoparticle catalysts stabilized in phosphonium and imidazolium ionic liquids : dependence of catalyst stability and activity on the ionicity of the ionic liquid
The catalytic activity and stability of phosphonium and imidazolium IL-stabilized Ru NPs depends on the ionicity of the IL.
