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.

In a one pot synthesis, 1,3-azaphospholo [5,1-a]isoquinoline (4) was obtained from the reaction of N-(alkoxycarbonylmethyl)isoquinolinium bromide (1) with PCl 3 in the presence of (C 2 H 5 ) 3 N. A crossed reaction confirms the formation of 4 proceeding via a 1,5-electrocyclization. Compound 4 under
