ABSTRACT:
A novel process is described for the homogeneous hydrogenation of carboxylic acid esters to primary alcohols utilizing anionic Group VIII metal hydride compositions as catalysts which contain phosphorus, arsenic or antimony organoligands. Use of these anionic catalysts allows the process to be conducted in solution under mild conditions of temperature and pressure with high selectivity and eliminates the disadvantages of utilizing heterogeneous catalysts. A process is also described for decarbonylating formate esters utilizing said compositions as catalysts.
