The oxidative reaction of fluoro-olefins with tricarbonyl(cyclobutadiene)-iron complexes
Abstract
Tetrafluoroethylene and hexafluoropropene react on irradiation with Fe(π-C4R4)(CO)3(R = H or Me) to give π-cyclobutenyl complexes, in which the fluorocarbon links the metal and the C4 ring. A similar reaction occurs with hexafluorobuta-1,3-diene, but a 1,3-fluorine shift also takes place. Hexafluoroacetone reacts with Fe(π-C4Me4)-(CO)3 to give [graphic omitted](CO)2(π-C4Me4), which reacts with phosphites or phosphines to give π-cyclobutenyl complexes.
