  The influence of steric bulk on the geometry of triarylphosphite-based palladacycles and their tricyclohexylphosphine adducts

  摘要：

  A range of complexes of the formula [PdCl2{P(OAr)(3)}(2)] have been synthesized in order to determine the effect of steric bulk on stereochemistry, one example [PdCl2{P(OC6H4-2-Bu-t)(3)}(2)] has been structurally characterized. Three palladacyclic complexes [{Pd(mu-Cl)-(kappa(2)-P, C-P(OC6H3R)(OC6H4R)(2))}(2)] have been synthesized (R = H, 2-Pr-t, 2-Bu-t) and two have been characterized by crystallography (R = H and Bu-t). The latter adopts the expected trans geometry while the former is cis. In this case, the driving force for the cis geometry seems to be intermolecular interactions in the crystal structure which are disrupted on substitution. We also report an unusual solvolysis reaction. (c) 2005 Elsevier Ltd. All rights reserved.

  C–P(O–m-CH3C6H3)(O–m-CH3C6H4)2}2], 3b. The trimeric palladium complexes very efficiently catalyzed the Suzuki–Miyaura and Hiyama reactions in ethane-1,2-diol and the Sonogashira cross-coupling in ionic liquids. The mercury test confirmed the homogeneous pathway of the Suzuki–Miyaura reaction, although Pd(0) nanoparticles were observed by TEM in the post-reaction mixture.
