## Abstract Novel 2โpyrazolines were obtained by the cycloaddition of diazomethane to bis(arylsulfonylethenyl)โsulfones (**3**) and 1โarylsulfonylโ2โstyrylsulfonylethenes (7). Dehydrogenation of 2โpyrazolines with chloranil gave pyrazoles.
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 orde
