  Synthesis and thermal decomposition of derivatives of acyloxytetraphenylantimony

  摘要：

  Acyloxy derivatives of tetraphenylantimony of the general formula Ph(4)SbOC(O)R (R = Alk or Ar) have been synthesized by the reaction of pentaphenylantimony with carboxylic acids. Thermolysis of the compounds obtained affords phenyl carboxylates and triphenylstibine in quantitative yields. One of these compounds (R = CH=CHPh) has been studied by X-ray structural analysis. In this compound, the Sb atom has a trigonal-bipyramidal coordination. The Sb-O(Ph)(eq) distances are in the range 2.103(4)-2.140(5) Angstrom; the Sb-C(Ph)(ax) bond length is 2.167(5) Angstrom. The fragment of the residue of cinnamic acid has a delocalized double bond in the carboxylate group.

  摘要：

  Catalytic C-phenylation of methyl acrylate to methyl cinnamate with the Ph4SbX complexes (X = F, Cl, Br, OH, OAc, O2CEt) in the presence of the palladium compounds PdCl2, Pd(OAc)(2), Pd-2(dba)(3), Pd(Ph3P)(2)Cl-2, and Pd(dppf)Cl-2 (dba is dibenzylideneacetone and dppf is bis(diphenylphosphinoferrocene)) was studied in organic solvents (MeCN, THF, DMF, MeOH, and AcOH). The highest yield of methyl cinnamate (73% based on the starting organometallic compound) was obtained for the Ph4SbCl-PdCl2 (1 : 0.04) system in acetonitrile.
