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.

friendly approach to building molecular complexity. In addition, there are significant cost and time saving benefits. However, unearthing multiple reactions that display substrate, reagent and solvent compatibility across two or more reactions, is not straightforward. This is even more pronounced when using catalysts, which by their nature, are present in small amounts and thus susceptible to poisoning
