Abstract

The phosphametallacycle 3, [ArN][RO]Mo=C-(t-Bu)P(OR)C(H)(t-Bu) (Ar=2,6-(i-Pr)₂-C₆H₃, R= Me-(CF₃)₂), is formed from the cycloaddition of tertbutylphosphaacetylene to the high-oxidation-state molybdenum alkylidene [ArN][RO]₂Mo=C(H)(t-Bu), accompanied by an alkoxide metal-to-ligand shift. The 1-phospha-3-molybdacyclobut-2-ene has been characterized by multinuclear NMR spectroscopy and its molecular structure determined by X-ray crystallographic analysis.
