Abstract

Reductive debromination of N-bromodifluoromethyl-4-dimethylaminopyridinium bromide, 1- bromodifluoromethyl-imidazole, 1-methyl-3-bromodifluoromethyl-imidazolium bromide and 1-bromodifluoromethyl-2-methyl-benzimidazole using tetrakis (dimethylamino) ethylene (TDAE) or tris (diethylamido) phosphite leads to new fluorinated carbanionic species, namely heteroarylium-N-difluoromethylides and heteroaryl-N-difluoromethyl anions. In the ...
