Synthesis and Structure of 1,2-Diphosphacyclopentenes.

-Transmetalation reactions of titanacyclobutenes (I) with two equivalent of dichlorophosphines affords selectivitly the title compounds (III) as single transisomers. The analogous reaction of titanacyclobutene with dichlorophenylstibine (IV) affords the corresponding distiba cyclopentene (VI) as well as stibacyclobutene (V) . -(DOXSEE, K. M.;
