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.
Claims15
A method for the synthesis of an amine compound or ammonia by a catalytic transfer hydrogenation, comprising (a) providing a mixture of a starting material comprising a nitrogen-containing compound, a hydrogen donor material, a catalyst selected from the group consisting of a catalytic form of carbon, a polyethylene glycol phase transfer agent, and mixtures thereof;
- and (b) heating the mixture 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 amine compound or ammonia.
A method for the synthesis of ammonia by catalytic transfer hydrogenation, comprising (a) providing a mixture of a nitrogen-containing compound, a hydrogen donor material comprising a hydrocarbon solvent, and a catalyst selected from the group consisting of a catalytic form of carbon, a polyethylene glycol phase transfer agent, and mixtures thereof;
- and (b) heating the mixture at a temperature of from 50.degree. to 150.degree. C. in the presence of at least one alkali or alkaline earth metal compound to cause reduction of the nitrogen-containing compound by catalytic transfer hydrogenation and form ammonia.
