2-Pyrazolines from 1,3-Dipolar Cycloaddition of Diazomethane to Arylsulfonylethenes

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.
