Silver-mediated oxidative C–H difluoromethylation of phenanthridines and 1,10-phenanthrolines†
Abstract
A silver-mediated oxidative difluoromethylation of phenanthridines and 1,10-phenanthrolines with TMSCF2H is disclosed. This C–H difluoromethylation of N-containing polycyclic aromatics constitutes an efficient method for the regioselective synthesis of difluoromethylated N-heterocycles.
