Abstract Aromatic and aliphatic alkynes can be halo-functionalized to α,α-dihalodimethyl ketals catalyzed by FeCl3 in excellent yields. MeOH is used as a nucleophilic solvent and N-halosuccinimide as the halogen source for this efficient transformation. The resulting α,α-dibromodimethyl ketals can be converted to the corresponding α,α-dibromoketones by treatment with 8% FeCl3 in silica gel.

Ketals of α,α-dihaloacetophenones are prepared in high yields from phenylethyne and N-halosuccinimide with catalytic quantities of p-toluenesulfonic acid.
