Hypervalent iodine(III) catalysis using an activated sulfoxide as a terminal oxidant has been developed for the metal-free synthesis of arylated furans. o-Nitrobenzenesulfonyl chloride (o-NsCl) or the generated acid activates the sulfoxide. 1-(Chloromethyl)-1,4-diazabicyclo[2.2.2]octan-1-ium 4-methylbenzenesulfonate (TEDA-OTs) contributes to the stability of the activated sulfoxide.
使用活化亚砜作为末端氧化剂的高价碘(III)催化已被开发用于芳基化呋喃的无金属合成。邻硝基苯磺酰氯 ( o -NsCl) 或生成的酸激活亚砜。1-(氯甲基)-1,4-二氮杂双环[2.2.2]辛-1-鎓4-甲基苯磺酸盐(TEDA-OTs)有助于活化亚砜的稳定性。
