Article abstract of DOI:10.1039/c39920001293

One-electron oxidation of 1 gives paramagnetic ⁺ 1⁺ in which the unpaired electron is highly delocalised onto the alkyne; the radical cation (1⁺; R = SiMe3) is an intermediate in the oxidative isomerisation of the vinylidene complex (η-C6Me6)> 2 to (1; R = SiMe3).
