Hydrazides from alkenes

The products from the reaction of alkene diazonium salts (266 X = SbCle or BF4) with acyl hydrazides are dependent on the nature of the substituents (R and R ) on the alkene <85CB4026, 89ZN(B)587>. With the 4-methoxystyryl derivative (266 R =OMe, R = 4-MeOQH4) only 1,3,4-oxadiazoles (267) are produced (17-40%), whereas with ketene acetals (266 R = OMe, R = OEt)... [Pg.771]
