Rate measurements for thermolysis of 4-azidothiazoles in p-xylene solution have identified neighbouring group effects from nitro (19-fold rate increase), phenyliminomethyl (16), formyl (4.5) and acetyl (2.2) substituents in the 5-position. These effects a

The aza-Wittig reaction of iminophosphoranes derived from 5-azido -4-formylazoles or 4-azido-5-formylazoles with heterocumulenes leads to functionalized fused pyrimidines.Iminophosphoranes 12, derived from 5-azido-4-formylpyrazole, react under mild condit
