A simple and mild one-pot procedure for the synthesis of carbamoyl azides from acyl chlorides utilizing a combination of tetrachlorosilane and sodium azide in acetonitrile at ambient temperature is reported. Under gentle heating 1-aryltetrazolin-5- ones were also obtained in one-pot process presumably via a [3 + 2] cycloaddition step.
