The dibromofluoromethylation of aryl Grignard reagents bearing electron-withdrawing groups with dibromodifluoromethane (CF2Br2) proceeded in the presence of LiBr. The reaction gave the corresponding alpha,alpha-dibromo-alpha-fluorotoluene derivatives through halogen exchange reaction of intermediate difluorobenzyl anions. (C) 2015 Elsevier B.V.

The bromodifluoromethylation of aromaticGrignardreagents having electron-withdrawing groups with dibromodifluoromethane (CF2Br2) was developed. The reaction proceeded to give the corresponding (bromodifluoromethyl)benzene derivatives via a difluorocarbene-mediated mechanism.
