Regiospecific Insertion of Phenylacetylene into the Zr—P bond of Cp2Zr{P(SiMe3)2}(Cl) and Derivatives of the Insertion Product (Z)-Cp2Zr{C(Ph) = C(H)P(SiMe3)2}(Cl)The reaction of Cp2Zr{P(SiMe3)2}(Cl) (1) with phenylacetylene in boiling toluene yields regiospecifically the insertion product (Z)-Cp2Zr{C(Ph) = C(H)P(SiMe3)2}(Cl) (2) which reacts with MeLi or nBuLi by forming the corresponding alkyl-substituted zirconocene derivatives (Z)-Cp2Zr{C(Ph) = C(H)P(SiMe3)2}(R) [R = Me (3), nBu (4)]. The attempt to prepare the C(Ph) = C(H)P(SiMe3)2- ligand directly from Li(THF)2P(SiMe3)2 and phenylacetylene yields HP(SiMe3)2 and LiC≡CPh. An X-ray structure determination of 2 and 3 was carried out.
