The cycloaddition reactions of (phenylsulfonyl)-1,2-propadiene (1) with various 1,3-dipoles have been investigated.MNDO calculations suggest that the reaction of the activated allene will proceed in a highly regioselective fashion and undergo cycloadditio

Alkynyl phenyl sulphones (4) react with the nitrile oxide (1), the nitrile imine (2), and sydnone (3) to afford predominantly or exclusively 4-phenylsulphonyl substituted cycloadducts (5), (7), and (9).The observed regioselectivity is discussed.
