✦ Synopsis

Perturbational molecular orbital methods have furnished a clue to the problems of reactivity and regioselectivity in 1,34polar cycloadditions. 1 Within the framework of frontier molecular orbital theory 2 semiquantitative correlations of mte data with orbital energy sepamtions were obtained. In order to check the

## Abstract Novel 2‐pyrazolines were obtained by the cycloaddition of diazomethane to bis(arylsulfonylethenyl)‐sulfones (**3**) and 1‐arylsulfonyl‐2‐styrylsulfonylethenes (7). Dehydrogenation of 2‐pyrazolines with chloranil gave pyrazoles.
