One ring no longer rules them all: Employment of 2.5–10 mol % of 4‐nitrobenzoic acid with phenylsilane led to the development of a room temperature catalytic Wittig reaction (see scheme). Moreover, these enhanced reduction conditions also facilitated the use of acyclic phosphine oxides as catalysts for the first time. A series of alkenes were produced in moderate to high yield and selectivity.
一个环不再完全统治一切:用2.5-10 mol%的4-硝基苯甲酸与苯基硅烷一起使用导致了室温催化Wittig反应的发展(参见方案)。此外,这些增强的还原条件还促进了首次将无环氧化膦用作催化剂。以中等至高收率和选择性生产了一系列烯烃。
