title: Synthesis and characterization of a stable cyclic gem-bis(phosphaylide): a 4π-electron three-membered heterocycle.
abstract: The mixed P,S-bisylide 1 reacts with phosphenium salts, affording phosphoniophosphinocarbenes, with elimination of diphenyl sulfide. Using a more compact cyclic phosphenium cation, the reaction leads to the formation of an original three-membered heterocycle featuring a gem-bisylide function. This molecule represents the first isolable analogue of the phosphirenyl anion derivative.
