The cycloaddition reactions of several phenylsulfonyl-substituted allenes with diazomethane have been investigated.The major products formed were identified as 3-(phenylsulfonyl)-4-methylene-2-pyrazolines.These pyrazolines engage in a variety of mechanist

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
