The perfluoro-1,2-di-t-butylvinyl radical has been generated by direct fluorination of perfluorodi-t-butylacetylene or by the addition of the perfluorodi-t-butyl radical to perfluoro-t-butylacetylene in perfluorodiamyl ether. The radical was identified by its ESR spectrum, and appeared to be quite stable in an inert medium.

It was established that the first stage of the reactions of anions1–6 with bromo- or iodoalkynes RC≡CX (X=Br or I) involved the transfer of the halogen atom from the sp-hybridized carbon atom to the transition metal atom to form carbonyl halides [(η5-C5R′5)(CO)3MX.
