Abstract

N&Ns: The C[BOND]F bond of trifluoromethylazoalkanes, in the presence of a hydrogen at the α carbon, is activated under basic conditions to form a difluoromethylene intermediate with a conjugated double bond, which is transformed in good yield to the corresponding 5-azido-(1-dialkylimino)tetrazole by reaction with NaN3.
