✦ Synopsis

Reaction of dibromoditluoromethane ( 1 ) with (trimethylsilyl)acetylene ( 2 ) initiated by ammonium persulfate/sodium formate ( (NH4)2S208/HCO2Na ) 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-difluorohomoallyi alcohols bearing a trimethylsilyl group 8 in high yields. In the presence of indium, 3b reacted with aldehydes to afford the coupling-reduction product gem-difluorohomoallyl alcohols 9.
