AbstractTreatment of anilido-phosphinimine-ligated yttrium mono(alkyl) complex 1a, LY(CH(2)Si(CH(3))(3))(THF) (L = o-(2,6-C(6)H(3)(i)Pr(2))NC(6)H(4)P(C(6)H(4))(C(6)H(5))N(2,4,6-C(6)H(2)Me(3))), with 2 equiv of phenylsilane in DME afforded methoxy-bridged complex 2, [LY(mu-OCH(3))](2), via the corresponding hydrido intermediate. When excess isoprene was added to the mixture of la and phenylsilane, a eta(3)-isopentene product, 3, LY(CH(2)C(CH(3))=CHCH(3))(THF), was isolated. A lutetium chloride, LLuCl(DME) (4), was generated through the reaction of lutetium mono(alkyl) complex 1b, LLu(CH(2)Si(CH(3))(3))(THF), with [Ph(3)C]-[B(C(6)F(5))(4)]center dot LiCl accompanied by the formation of [Li(DME)(3)](+)[B(C(6)F(5))(4)](-). Metathesis reaction of 1b with excess AlMe(3) at room temperature gave a methyl-terminated counterpart, 5, LLu(CH(3))(THF)(2). In all these reactions, the Ln-C(phenyl) bonds of complexes 1 remained untouched. However, protonolysis of complex 1b with 2 equiv of phenylacetylene in DME provided a lutetium bis(acetylide), LHLu(C CPh)(2)(DME) (6), and the linkage of the Ln-C(phenyl) bond was cleaved, indicating that the activated C-H bond was recovered.
