摘要

Abstract: The course of hydrogenation of dehydroamino acids by cationic rhodium complexes derived from bis (1, 2-diphenylphosphino) ethane has been studied by phosphorus and carbon NMR. The parent complex reacts with hydrogen (1 atm) in methanol to form norbornane and the corresponding biphosphine rhodium solvate. Addition of (Z)-a- benzamidocinnamic acid causes displacement of solvent and formation of the ...
