TRANSFER HYDROGENATION PROCESS AND CATALYST |
摘要 |
A catalytic transfer hydrogenation process is provided. The catalyst employe d in the process is a metal cyclopentadienyl complex which is coordinated to defined bidentate ligands. Preferred metals include rhodium, ruthenium and iridium. Preferred bidentate ligands are diamines and aminoalcohols, particularly those comprising chiral centres. Th e hydrogen donor is advantageously a secondary alcohol or a mixture of triethylamine and formic acid. The process can be employed to transfer hydrogenate ketones and imines, which are preferably prochiral. Catalysts for use in such a process are also provided.
