Sustainable catalysis

Sustainable catalysis

This focused collection of papers is devoted to recent developments in ‘green chemistry’, especially the applications of catalytic methods, involving both chemoand biocatalysis. The development of catalytic processes is an important current theme in organic chemistry, since it aims to reduce the environmental impact of the industrial synthesis of chemicals and polymers by replacing stoichiometr...

Heterogeneous catalysis for sustainable biodiesel production via esterification and transesterification.

Concern over the economics of accessing fossil fuel reserves, and widespread acceptance of the anthropogenic origin of rising CO2 emissions and associated climate change from combusting such carbon sources, is driving academic and commercial research into new routes to sustainable fuels to meet the demands of a rapidly rising global population. Here we discuss catalytic esterification and trans...

Micellar catalysis-enabled sustainable ppm Au-catalyzed reactions in water at room temperature.

Several ppm level gold-catalyzed reactions enabled by the ligand HandaPhos can be performed at room temperature in aqueous nanoreactors composed of the surfactant Nok. Variously substituted allenes undergo cycloisomerization leading to heterocyclic products in good yields. Likewise, cyclodehydration is also illustrated under similar conditions, as is an intermolecular variant, hydration of term...

Synthesis of α-iodoketals from methyl ketones via sustainable and orthogonal tandem catalysis.

A highly efficient method for the direct synthesis of α-iodoketals from methyl ketones has been developed via sustainable integration of orthogonal tandem catalytic reactions: copper(II) oxide catalyzed iodination reaction and the subsequent excess or regenerated iodine catalyzed regioselective ketalization reaction.
