bis[(diphenylphosphinoyl)methyl] sulfides, selenides, and tellurides is described by the reaction of (diphenylphosphinoyl)methyl p-toluenesulfonate with sodium chalcogenides. The title compounds are subjected to Horner–Wittig-type reactions with aldehydes and ketones to give symmetrical divinylic sulfides, selenides, and tellurides with preferential (E) stereochemistry. Unsymmetrical divinylic sulfides can be prepared
新的双[(二苯基膦酰基)甲基]硫化物、硒化物和碲化物的制备通过对甲苯磺酸(二苯基膦酰基)甲酯与硫属元素钠的反应进行描述。标题化合物与醛和酮进行 Horner-Wittig 型反应,得到对称的二乙烯基硫化物、硒化物和碲化物,具有优先 (E) 立体化学。不对称二乙烯基硫化物可以通过使用合适的羰基化合物来制备。 (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2007)
