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