A practical and unified strategy has been described for the preparation of mono- and difluoromethylated phenanthridine derivatives using a visible-light-promoted alkylation and decarboxylation sequence from biphenyl isocyanides with ethyl bromofluoroacetate (EBFA) or ethyl bromodifluoroacetate (EBDFA). These reactions could be carried

Synthetic strategies toward 4-substituted 3,3-difluoropiperidines were evaluated. 4-Alkoxymethyl- and 4-aryloxymethyl-3,3-difluoropiperidines were synthesized via 1,4-addition of ethyl bromodifluoroacetate to 3-substituted acrylonitriles in the presence of copper powder, followed by borane reduction of the cyano substituent, lactamization, and reduction of the lactam.

A practical and highly enantioselective Reformatsky reaction of ethyl bromodifluoroacetate with imines using a cheap and commercially available amino alcohol ligand is described. A variety of α,α-difluoro-β-lactams were obtained in up to 74% yield with high enantioselectivity in excess of
Copper-mediated reaction of 2-halopyridines with ethyl bromodifluoroacetate.
