Abstract

Abstract : A highly reactive, transiently formed terminal phosphinidene complex reacts with triethylamine to form a primary phosphane complex, eventually. The dehydrogenation is explained by a detailed, DFT-based mechanistic proposal. Abstract : Reaction of a transiently formed terminal phosphinidene complex with triethylamine resulted in the formation of an sp 3 C–H insertion product, as revealed by 31 P NMR spectroscopy, which was isolated as semi-solid compound. However, if the reaction was continued for 24 h, a primary phosphane complex was obtained eventually. The compounds were characterised by NMR spectroscopy and mass spectrometry. Formation of the final products is explained by a mechanistic proposal based on DFT calculations.
