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. © 2011 American Chemical Society.
