| Abstract: | 1-Methoxy-4-aryltetrazolyldienes have been subjected to oxidative degradation to yield tetrazolyl acroleins. These compounds when reacted with 1,1-dimethylhydrazine gave 1-dimethylamino-4-aryltetrazolyl-1-azadienes. Both the acroleins and the new 1-azadienes underwent ring transformation in reaction with fumaronitrile to afford pyrazolyl derivatives. |
