Tetrafluoroethylene, reaction with metal

The neutral hydrides are to some extent atypical in that the metal hydrogens do not show the normal addition reactions with diazomethane or tetrafluoroethylene. The complexes (XX), however, show... 

The complex [(acac)Rh(PhjPMe)2] reacts with tetrafluoroethylene and chlorotrifluoroethylene to yield the rhodacyclopentane complexes (131), but with bromotrifluoroethylene, complex (132) is formed. In the reaction with 1,2-dichlorotetrafluorocyclobutene, transfer of chlorine to metal occurs, giving the vinylic complex (133). The complex [(acac)Rh(Ph2PMe)j] reacts with only one mole of hexafluoroacetone, yielding (134), but with the corre-... 

One complex with a metal—metal bond that has been added to an olefin is cobalt octacarbonyl. It reacts with tetrafluoroethylene and it seems reasonable that this is an insertion reaction but again it has not been proved. 

Trifluorovinyl aromatic ethers can be prepared by several methods. In 1966, phenyl trifluorovinyl ether was first obtained by the reaction of an alkali metal phenoxide (PhONa or PhOK) with tetrafluoroethylene in Parr bombs [25]. The yield of the reaction was mediocre because of side reactions, where reactive fluorocarbanions are trapped by the available proton donors in the reaction system to give saturated 1,1,2,2-tetrafluoroethyl phenyl ethers (Scheme 14.1). 

In the addition of transition metal hydrides to unsaturated fluorocarbons reaction proceeds best with tetrafluoroethylene. So far most of the studies have been carried out with manganese pentacarbonyl hydride. By addition of this hydride to the double bonds of either chlorotrifluoroethylene or... 

Iron, Ruthenium, and Osmium.—Cyclo-octafluorotetramethylenetetra-carbonyliron (100), formed in the thermal reaction of tetrafluoroethylene with iron carbonyls, was one of the earliest reported fluoro-organo-derivatives of a transition metal. It may be more efficiently synthesized in a photochemical reaction. Ligands displace carbon monoxide from complex (100) to form complexes of the types (101) [L = PPhj, AsPhj,...
