Abstract

Abstract Methylidynephosphane (2) is generated under flash pyrolytic conditions by cleavage of isobutene from the phosphaalkyne (1) or by elimination of hydrogen chloride from dichloromethylphosphine (3). It undergoes [3+ 2]-cycloaddition reactions with stable dipoles eq. diazo compounds (2+ 4a, b→ 5a, b), methyl azide (2+ 7→ 8), benzonitriloxide (2+ 10→ 12, 1: 2-adduct) and 3-methyl-2, 4-diphenyl-1, 3-oxazolium-5-olate (2+ 13→ 15) ...
