Abstract

By treating diphosphinito[PCP]-pincer ligand,(Ph₂P(ortho-C₆H₄))₂CH₂(1) with CoMe(PMe₃)₄ or CoMe₃(PMe₃)₃ the same Csp³-H bond activation product[PCP]Co(I)(PMe₃)(2) was obtained at room temperature. Treatment of 2 with C₆Cl₆, EtBr or n-BuBr and CH₃I gave rise to the single electron oxidation addition products[PCP]Co(II)X(PMe₃)[X=Cl(3), Br(4) and I(5)]. The molecular structures of 2~6 were confirmed by X-ray diffraction analysis.

Key words: Csp³-H activation, pincer complex, cobalt complex
