Abstract
Novel molybdenum alkylidyne [(F3C)Me(2)-CO]Mo-2(C-t-Bu)[N(Ar)P=C(H)(CM e(2)Ph)] (Ar = 2,6-(i-Pr)(2)C6H3; 3b) is formed in the reaction of ter t-butylphosphaalkyne 2 with molybdenum alkylidene 1b. Alkylidyne 3b, w hich contains a formal (phosphaalkenyl)amido ligand, rearranges quanti tatively at elevated temperature to form the alkoxide-shifted phospham olybdacyclobutene 4b. Complexes 3b and 4b have been fully characterize d by spectroscopic and X-ray crystallographic analysis; cleavage of th e P=C-t-Bu triple bond in complex 3b is confirmed.
