Herein, we report the first example of synthesis of N-substituted lactams via an acceptorless dehydrogenative coupling of diols with primaryamines in one step, which was enabled by combining Ru3(CO)12 with a hybrid N-heterocyclic carbene–phosphine–phosphine ligand as the catalyst.

The first general method for the Pd-catalyzedamination of aryl tosylates and benzenesulfonates was developed utilizing ligand 1, which belongs to a new generation of biaryl monophosphine ligands. In addition, the new catalyst system for the first time enables amidation of aryl arenesulfonates and aqueousamination protocols that do not necessitate the use of cosolvents. The substrate scope has been
Pd催化芳基甲苯磺酸酯和苯磺酸酯胺化的第一种通用方法是利用配体1开发的,该配体属于新一代联芳基单膦配体。此外,新的催化剂系统首次实现了芳基芳烃磺酸盐的酰胺化和不需要使用助溶剂的水性胺化方案。底物范围已显着扩大到包括含有伯酰胺和游离羧酸基团的芳基卤化物。在多功能基板的情况下,Pd 催化的胺化可以提供与 Cu 催化的 CN 键形成过程互补的选择性。

Through the interception of amide ylides with sulfonamides, we herein report the first general example of an intermolecular condensation reaction between sulfonamides and amides. Beyond formamides, this approach was successfully applied to a variety of lactams and linear amides, giving rise to a broad array of (E)-N-sulfonyl amidines.
