Alkynyl phenyl selenides, easily prepared from terminal alkynes, react with p-toluenesulfonic acid to afford (Z)-α-(phenylseleno)vinyl p-toluenesulfonates. The reactions of these compounds with phenylselenyl sulfate in the presence of alcohols or water give the corresponding α-phenylseleno esters or acids, respectively.
炔基苯基硒化物可以从末端炔烃中易于合成,与对甲苯磺酸反应生成(Z)-α-(苯基硒代)乙烯对甲苯磺酸盐。这些化合物与苯基硒酸硫酯在醇或水存在下的反应,分别生成相应的α-苯基硒代酯或酸。
