CYCLOADDITION WITH SIMULTANEOUS ELIMINATION OF TRIPHENYLPHOSPHINE IN THE REACTION OF BETAINES - α-(TRIPHENYLPHOSPHONIO)ALKYLDITHIOCARBOXYLATES - WITH ACTIVATED ACETYLENES

α-(Triphenylphosphonio)alkyldithiocarboxylates react with acetylenes activated by electron-withdrawing substituents by a mechanism of anionic -cycloaddition with the simultaneous elimination of triphenylphosphine and the formation of 2-alkylidene-1,3-dithioles.
