Transformations of the cyclo-P₄ ligand in [Cp'''Co(η⁴-P₄)].

ABSTRACT: The reactivity of the cyclo-P₄ ligand complex [Cp'''Co(η⁴-P₄)] (1) (Cp''' = 1,2,4-tri-tert-butyl-cyclopentadienyl) towards reduction and main group nucleophiles was investigated. By using K[CpFe(CO)₂], a selective reduction to the dianionic complex [(Cp'''Co)₂(μ,η³:η³-P₈)]^2- (2) was achieved. The reaction of 1 with ^t BuLi and LiCH₂SiMe₃ as carbon-based nucleophiles yielded [Cp'''Co(η³-P₄R)]^- (R = ^t Bu (4), CH₂SiMe₃ (7)), which, depending on the reaction conditions, undergo subsequent reactions with another equivalent of 1 to f
