On the pathway of the 1–5 migration of a Cp* ligand.
Journal of the Chemical Society, Dalton Transactions 2000 (15), pp. 2493-2494.
The thermolysis and photolysis, respectively, of the phosphinidene complex [Cp*P2] 1 in the presence of MeCCMe leads to the three-membered heterocycle [(2-CH2C5Me4)W(CO)4CPW(CO)5] 4 with an unusual 2-coordinated CH2C5Me4 ligand formed by a 1,4-sigmatropic hydrogen shift; the crystal structure and the spectroscopic data of 4 are discussed.
