The reaction of vinyl halides with phenylselenenyl chloride in alcohols affords α-alkoxy acetals and diphenyl diselenide which can be oxidized to PhSe cations by nitrate or persulfate anions. The reaction can be carried out with catalytic amounts of PhSeCl or PhSeSePh. The reaction proceeds through the formation of the methoxyselenenylation product which then suffers solvolysis. Under controlled conditions
卤乙烯与醇中的苯基硒烯基氯反应,得到α-烷氧基缩醛和二苯基二硒化物,它们可被硝酸根或过硫酸根阴离子氧化成PhSe阳离子。该反应可以用催化量的PhSeCl或PhSeSePh进行。反应通过形成甲氧基硒基化产物而进行,然后其遭受溶剂分解。在受控条件下,从β-溴苯乙烯与PhSeCl在甲醇中的反应中分离出1-苯基-1-甲氧基-2-溴-2-苯基硒烯乙烷。据报道该α-卤代亚硒酸酯的数个去硒烯基化反应。
