DOI: 10.1039/b809088b
The details of a new alternative and greener route to a Resmethrin intermediate are reported. A quantitative comparative assessment of this new route over the best existing one is also reported.
Purity specification methods for ionic liquids
Annegret Stark, Peter Behrend, Oliver Braun, Anja Müller, Johannes Ranke, Bernd Ondruschka and Bernd Jastorff,
Green Chem., 2008, 10, 1152
DOI: 10.1039/b808532c
An array of various quantitative analytical methods for the determination of the purity has been developed and compiled to facilitate the specification of organic and inorganic starting materials, solvents, water and decomposition products in ionic liquids.
The role of the support in achieving high selectivity in the direct formation of hydrogen peroxide
Edwin Ntainjua N., Jennifer K. Edwards, Albert F. Carley, Jose Antonio Lopez-Sanchez, Jacob A. Moulijn, Andrew A. Herzing, Christopher J. Kiely and Graham J. Hutchings,
Green Chem., 2008, 10, 1162
DOI: 10.1039/b809881f
The selection of the support for the active Au–Pd nanoparticles is shown to be a major factor in designing selective catalysts for the direct synthesis of hydrogen peroxide.
Evaluating the greenness of alternative reaction media
Denise Reinhardt, Florian Ilgen, Dana Kralisch, Burkhard König and Günter Kreisel,
Green Chem., 2008, 10, 1170
DOI: 10.1039/b807379a
The application of alternative reaction media (ionic liquids, carbohydrate–urea melts, solvent-free alternative) in a Diels–Alder reaction is evaluated and compared to conventional solvents with the help of an economic and ecological screening method in order to accentuate opportunities and challenges.
Synthesis of dialkyl ethers by decarboxylation of dialkyl carbonates
Pietro Tundo, Fabio Aricò, Anthony E. Rosamilia and Sofia Memoli,
Green Chem., 2008, 10, 1182
DOI: 10.1039/b809271k
The decarboxylation reaction of dialkyl carbonates to give their related ethers was investigated. The influence of several reaction parameters on the selectivity was studied. Symmetrical and dissymmetrical dialkyl ethers can be synthesised with yields up to 80%.
Synthesis of biobased epoxy and curing agents using rosin and the study of cure reactions
Honghua Wang, Bo Liu, Xiaoqing Liu, Jinwen Zhang and Ming Xian,

DOI: 10.1039/b807019a
Many toxicity studies have been performed on the commonly used ionic liquid, 1-butyl-3-methylimidazolium, yet none have determined the maternal or developmental toxicity.
A CO2/H2O2-tunable reaction: direct conversion of styrene into styrene carbonate catalyzed by sodium phosphotungstate/n-Bu4NBr

DOI: 10.1039/b807108j
A facile synthesis of styrene carbonate was realized directly from styrene and CO2 in an environmentally benign manner. Selective formation of carbonate 1a and preferentially producing benzoate 1b could be controlled by subtly tuning the quantities of CO2 and H2O2.
One-pot copper nanoparticle-catalyzed synthesis of S-aryl- and S-vinyl dithiocarbamates in water: high diastereoselectivity achieved for vinyl dithiocarbamates

DOI: 10.1039/b809200a
Copper nanoparticles efficiently catalyze the three-component condensation of an amine, carbon disulfide and aryl iodide or styrenyl bromide in water to produce the corresponding S-aryl or S-styrenyl dithiocarbamates in high yields. High diastereoselectivities are achieved for styrenyl derivatives.
