Cycloaddition between phenyl azide and 2H-thiopyran-3(6H)-one is followed by isomerization of the adduct to 5-anilino-4-diazo-4,5-dihydro-2H-thiopyran-3(6H)-one 4.On heating, 4-(anilinomethylene)-4,5-dihydrothiophen-3(2H)-one 5 and N-phenyl-2,5-dihydrothiophene-3-carboxamide 7 are formed by carbenoid rearrangements
