Synthesis, structure, and thermal destruction of aroxytetraphenylstiboranes

Article abstract of DOI:10.1007/BF00696931

A series of aroxytetraphenylstiboranes, Ph4SbOAr, were obtained by the reaction of pentaphenylstiborane with phenols at ca.20 deg 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-Br2, 2,4-Cl2, 2-NO2, 4-OPh) produces predominantly simple diaryl ethers of asymmetric structure in 58percent, 90percent, 32percent, and 60percent yields, respectively.
