Dilithium amides have been developed as a bespoke and general ligand for iron-catalyzed Kumada–Tamao–Corriu cross-coupling reactions, their design taking inspiration from previous mechanistic and structural studies. They allow for the cross-coupling of alkyl Grignard reagents with sp2-hybridized electrophiles as well as aryl Grignard reagents with sp3-hybridized electrophiles. This represents a rare

The Ph3P/ICH2CH2I system-promoted dehydroxylative substitution of alcohols was achieved to construct C–O, C–N, C–S and C–X (X = Cl, Br, and I) bonds. Compared with the previous approaches such as the Appel reaction and Mitsunobu reaction, this protocol offers some practical advantages such as safe operation and a convenient amination process.
通过Ph 3 P / ICH 2 CH 2 I系统促进的醇的脱羟基取代反应,可构建C–O,C–N,CS–S和C–X(X = Cl,Br和I)键。与之前的方法(如Appel反应和Mitsunobu反应)相比,该方案具有一些实用的优点,例如操作安全和便捷的胺化过程。
