  Triamidoamine-supported zirconium complexes in the catalytic dehydrocoupling of 1,2-bisphosphinobenzene and -ethane

  摘要：

  The readily prepared zirconium complex, [K-5-(Me3SiNCH2CH2)(2)NCH2CH2NSiMe2CH2]Zr (1), is an effective precatalyst in the dehydrocoupling of o-bisphosphinobenzene and 1,2-bisphosphinoethane to the known intercalated products. The phosphanido complex (N3N)Zr[K-2-1,2-PH(PH2)C6H4] (N3N=N(CH2CH2NSiMe3)(3)(3-)), 2 was prepared independently by reaction of 1 with o-bisphosphinobenzene. Complex 2 was identified as an intermediate zirconium complex in the catalytic dehydrocoupling of o-bisphosphinobenzene. Likewise, previously reported (N3N)Zr(PHCH2CH2PH2) (3) was identified in the catalytic dehydrocoupling of 1,2-bisphosphinoethane. Investigation of the thermal decomposition of 2 and the reactivity of 2 with stoichiometric o-bisphosphinobenzene suggest that the catalysis proceeds via sequential P-P bond forming steps. The solid state structure of 2, which features a six-coordinate (N3N)Zr-complex, is reported. (C) 2009 Elsevier Ltd. All rights reserved.
