Nitrile imines and nitrile oxides by intermolecular cycloaddition reaction with aryl styryl sulfones 1 lead to the formation of tetrasubstituted pyrazolines 3 and trisubstituted isoxazolines 6. The 3 and 6 on dehydrogenation with chloranil in xylene gave

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.
