Glycerol Selective Oxidation Under Acidic Conditions

Introduction Apart from the decline of fossil fuel energy resources, there is the added problem, recognised internationally, that fossil fuels are responsible for the greenhouse effect and global warming. Therefore, new alternative ways must be developed to satisfy not only energy needs and the production of chemicals but also for more benign effects on the environment. An approach already bein...

A fast, simple and convenient procedure for the synthesis of fused pyrimidinone derivatives by using [Hmim][HSO4] as a green, efficient and reusable catalyst under solvent-free conditions

In the present of methylimidazolium hydrogen sulfate, the synthesis of arylidene heterobicyclic pyrimidinones is studied by condensation of aromatic aldehyde, cyclopentanone, and urea or thiourea. Using solvent-free conditions, non-toxic and inexpensive materials, simple and clean work-up, short reaction times and good yields of the products are the advantages of this method.
