A unique diphosphametallabicyclobutane complex results from the reaction of the Schrock tungsten neopentylidene with excess P≡C-t-Bu, in contrast to phosphaalkyne reaction products with similar molybdenum alkylidenes. A mechanistic rationalization for the complex, which has been structurally characterized by NMR spectroscopy and single-crystal X-ray analysis, is postulated in terms of a ring-opening metathesis-like mechanism.
