Alkylation of sulfenates proved to be a good method for synthesis of alkoxysulfonium ion not obtainable by alkylation of sulfoxides. Dialkoxy- and alkoxyamino-sulfonium ions were prepared by alkylation of sulfinates and sulfinamides. Ethoxy- and methoxymorpholinophenylsulfonium tetraphenylborates were obtained as high-melting crystals, which almost quantitatively alkylated amines at room temperature
亚磺酸盐的烷基化被证明是合成烷氧基锍离子的好方法,而亚砜的烷基化无法获得。二烷氧基-和烷氧基氨基-锍离子通过亚磺酸盐和亚磺酰胺的烷基化制备。乙氧基-和甲氧基吗啉代苯基锍四苯基硼酸盐作为高熔点晶体获得,在室温下几乎定量地烷基化胺。确定了 RR'\overset⊕S-OCHAHBR" 和 RR'\overset⊕S-N(R")CHAHBR'" 的 PMR 光谱,并检查了 δA-δB 和 (R,R') 之间的关系。
