Phosphametallocenes: from discovery to applications
摘要:
This account describes the development of phosphametallocene chemistry from the discovery of phosphacymantrenes in 1976 and phosphaferrocenes in 1977, to the preparation of paramagnetic and main group derivatives and to the development of catalytic applications starting in 1995. It does not intend to be comprehensive and is mainly focused on the work of the author's group. (C) 2002 Elsevier Science B.V. All rights reserved.
Monophospholyl Analogs of Cobaltocenium, Rhodocenium, and Iridocenium Cations. Molecular Structures of [MCp*(η5-PC4H2tBu2)]+BPh4- (M = Co, Rh)
摘要:
Monophosphametallocenium cations of the cobalt group are easily prepared through metathesis of bis(eta(5)-2,5-di-tert-butylphospholyl)lead (1) with [MCp*X-2](2) (M = Cd, Rh, fr). Crystal structure analyses confirm their metallocene structures, and electrochemical studies show that [CoCp*(PC(4)H(2)tBu(2))](+) (2) undergoes reversible reduction to a long-lived product at a potential of -0.74 V (vs SCE).
