ABSTRACT:
Methods for synthesis of chemical compounds by catalytic transfer hydrogenation comprise forming a mixture of a starting material, a hydrogen donor material and a catalyst. The catalyst is selected from a catalytic form of carbon, a polyethylene glycol phase transfer agent, and mixtures thereof. The mixture is heated at a temperature of from 30.degree. to 400.degree. C. in the presence of at least one alkali or alkaline earth metal compound to cause reduction of the starting material by catalytic transfer hydrogenation and form the desired chemical compound product.
