Novel molybdenum alkylidyne [(F3C)Me2-CO]2Mo(C-t-Bu)[N(Ar)P=C(H)(CMe 2Ph)] (Ar = 2,6-(i-Pr)2C6H3; 3b) is formed in the reaction of tert-butylphosphaalkyne 2 with molybdenum alkylidene 1b. Alkylidyne 3b, which contains a formal (phosphaalkenyl)amido ligand, rearranges quantitatively at elevated temperature to form the alkoxide-shifted phosphamolybdacyclobutene 4b. Complexes 36 and 4b have been fully characterized by spectroscopic and X-ray crystallographic analysis; cleavage of the P≡C-t-Bu triple bond in complex 3b is confirmed.
