The reaction of diphenylcyclopropenone oxime (1a) with acetyl or tosyl isocyanate, carboxylic anhydrides, or nitrohalobenzenes yielded the cyclopropenone O-substituted oxime derivatives.Treating with thionyl bromide and chloride 1a gave 3-haloacrylonitriles.Whereas 1a as well as other cyclopropenone oximes, were stable under acidic conditions, heating in methanolic sodium hydroxide gave the ring-opened α,α-dimethoxyketones oximes.

Previously we have examined the action of amines on Z α-cyano β-nitrostilbenes (1).We now would like to report the results of our studies on the action of two other nucleophiles (alcohols and thiols) on these stilbenes derivatives.At room temperature in a
