Cycloaddition of phosphaalkynes to high-oxidation-state metal alkylidenes: Synthesis and characterization of a unique phosphametallacyclobutene via an alkoxide ligand shift

The phosphametallacycle 3, [ArN][RO]Mo=C(t-Bu)P(OR)C(H)(t-Bu) (Ar = 2, 6-(i-Pr){sub 2}-C{sub 6}H{sub 3}, R = CMe(CF{sub 3}){sub 2}), is formed from the cycloaddition of tert-butylphosphaacetylene to the high-oxidation-state molybdenum alkylidene [ArN][RO]{sub 2} Mo=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. 20 refs., 2 figs.
