Silicon-mediated Direct Conversion of Acyl Chlorides to Carbamoyl Azides or/and Tetrazolinones under Mild Conditions
A simple and mild one-pot procedure for the synthesis of carbamoyl asides from acyl chlorides utilizing a combination of tetrachlorosilane and sodium aside 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.
