[Figure not available: see fulltext.] A method was developed for the synthesis of 1,5-dialkyl(cycloalkyl,phenyl)-2-phenyl-6-oxa-2-phosphabicyclo[3.1.0]hexane 2-oxides from alkynes, involving the epoxidation of unsaturated cyclic organophosphorus compounds with m-chloroperbenzoic acid. The organophosphorus compounds were obtained by a reaction sequence consisting of catalytic cycloalumination of symmetrical acetylenes with triethylaluminum in the presence of bis(cyclopentadienyl)zirconium(IV) dichloride catalyst leading to the formation of 2,3-disubstituted aluminacyclopent-2-enes and in situ reaction of the latter with dichlorophenylphosphine.

A preparative one-pot method for the synthesis of 2,3-dialkyl-substituted phosphol-2-enes by catalytic cycloalumination of symmetric acetylenes with AlEt3 catalyzed by Cp2ZrCl2 is developed. The reaction gives the corresponding aluminacyclopentenes, which then react in situ with phosphorus dihalides.

Zirconacyclopentenes, which are easily prepared from alkynes, alkenes, and zirconocene compounds, reacted with dichlorophenylphosphine to give 2-phospholene in high yields. The reaction was performed conveniently in one-pot from an alkyne, alkene, dichlor
