A bismuth(III) compound with a reactive (aryl)2Bi−OPh functional group has been synthesized, isolated, and characterized. It has been investigated as a catalyst using the dehydrocoupling of silanes with alcohols or TEMPO as model reactions. In contrast to bismuth compounds with (aryl)2Bi−EPh functional groups (E=S, Se, Te), it shows catalytic activity in thermally- and photochemically-initiated transformations
合成、分离并表征了具有反应性(芳基) 2 Bi-OPh 官能团的铋(III)化合物。已使用硅烷与醇或 TEMPO 的脱氢偶联作为模型反应,对其作为催化剂进行了研究。与具有(芳基) 2 Bi−EPh 官能团(E=S、Se、Te)的铋化合物相比,它在热和光化学引发的转化中表现出催化活性,解决了不同的反应途径。
