Alkylidyne 3b, which contains a formal (phosphaalkenyl)amido ligand, rearranges quantitatively at elevated temperature to form the alkoxide-shifted phosphamolybdacyclobutene 4b. Complexes 3b 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. %I ACS Publications
