Reaction of dibromodifluoromethane (1) with (trimethylsilyl)acetylene (2) initiated by ammonium persulfate/sodium formate () yield the addition-reduction product (3a), tribromide compound (3b) and the non-fluorinated compound (4) which could be separated by careful distillation. The reaction appears to be initiated by CO2•-. Indium mediated coupling of 3a with aldehydes gave the corresponding gem-difluorohomoallyl
