Metal carbonyl chemistry. Part V. Reactions of fluoro-olefins with octacarbonyldicobalt

Abstract

Octacarbonyldicobalt reacts with the fluoro-olefins CF2:CF2, CF2:CFCl, or CF2:CFBr at 100° to give nonacarbonyl-(trifluoromethylcarbon)tricobalt, CF3·CCo3(CO)9, in high yields. At lower temperatures, or with a shorter reaction time, tetrafluoroethylene gives mainly µ-tetrafluoroethylenebis(tetracarbonylcobalt), (OC)4Co·CF2·CF2·Co(CO)4, which rearranges quantitatively when heated in vacuo to form the novel compound, µ-tetrafluoroethylidene-µ-carbonyl-bis(tricarbonylcobalt), (OC)3Co(CF·CF3)(CO)Co(CO)3. The mechanism of formation of CF3·CCo3(CO)9 from tetrafluoroethylene is discussed in terms of these intermediate compounds.
