1λ5,3λ5‐Diphospholium ions

1λ5,3λ5‐Diphospholium ions One example each is given for the reaction of bromoacetylenes and ethynyl‐phenyliodonium tosylates with bis(diphenyl phosphino)methane. The yellow crystalline 1:1‐addition products are diphospholium salts. They readily and selectively hydrolyze to give 2‐phosphinoylethenyl phosphonium salts. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Heteroatom Chemistry Wiley

Abstract

One example each is given for the reaction of bromoacetylenes and ethynyl‐phenyliodonium tosylates with bis(diphenyl phosphino)methane. The yellow crystalline 1:1‐addition products are diphospholium salts. They readily and selectively hydrolyze to give 2‐phosphinoylethenyl phosphonium salts.
