  Synthesis, structure, and thermal destruction of aroxytetraphenylstiboranes

  摘要：

  A series of aroxytetraphenylstiboranes, Ph(4)SbOAr, were obtained by the reaction of pentaphenylstiborane with phenols at similar to 20 degrees C. The thermolysis of these compounds gives O- or o-C-phenylation products. The thermolysis of stiboranes, which incorporate aryl groups containing electron-withdrawing substituents (Ar = 2,4-Br-2, 2,4-Cl-2, 2-NO2, 4-OPh) produces predominantly simple diaryl ethers of asymmetric structure in 58%, 90%, 32%, and 60% yields, respectively.

  Tetraphenylantimony aroxides Ph4SbOAr, where Ar = C6H4C6H7 (I), C6H2(Br-2-2,6)(tert-Bu-4) (II), C6H2(Br-2-2,6)(NO2-4) (III), and C6H3(NO2)(2)-2,4 (IV), have been synthesized by the reaction of pentaphenylantimony with 4-cyclohexadienylphenol, 2,6-dibromo-4-tert-butylphenol, 2,6-dibromo-4-nitrophenol, and 2,4-dinitrophenol. The antimony atoms in molecules of complexes I-IV have a differently distorted trigonal bipyramidal coordination to the oxygen atoms of aroxy groups in axial positions. The OSb. angles are 177.63(13)degrees (I), 174.29(7)degrees (II), 177.8(6)degrees (III), and 174.01(7)degrees (IV). The Sb-O bond length is 2.117(3)angstrom (I), 2.2613(15)angstrom (II), 2.409(11)angstrom (III), and 2.4296(15)angstrom (IV).
