Abstract
The reaction of (phenylazo) stilbene and copper (II) chloride wih some dienophiles produced benzaldehyde and N-(α-chlorobenzylidene)-N'-phenylhydrazine, instead of the expected (4+ 2)-cycloaddition products. By reaction of some (arylazo) alkenes and copper (II) chloride in acetone at 0° C, the relative N-(α-chlorobenzylidene)-N'-arylhydrazine derivatives were successfully obtained in high yields.
