✦ Synopsis
One example each is given for the reaction of brornoacetylenes and ethynyl-phenyliodoniurn tosylates with bis(dipheny1 phosphino)methane. The yellow crystalline 1 :I -addition products are diphospholiurn salts. They readily and selectively hydrolyze to give 2- phosphinoylethenyl phosphoniurn salts.

The 1,2-azaphosphinine, 9, and the 1,3-diphosphinine, 10, can be isolated from a mixture resulting rom diphosphete, 1, and ethyl isothiocyanate. The reaction of 1 with phenyl isothiocyanate yields the 1,2azaphosphinine, 16. Mechanisms for the formation of the compounds 9, 10, and 16 are suggested. T
