A visible-light-driven carboxylation of aryl and alkenyl triflates with CO2 is developed by using a combination of Pd and photoredox catalysts. This reaction proceeds under mild conditions and can be applied to a wide range of substrates including acyclic alkenyl triflates.

We report the synthesis of N-(α,β-unsaturated acyl)-substituted sulfonimidamidesthrough a Pd-catalyzedcarbonylation protocol, employing sulfonimidamides as nucleophiles usingCO gas released exsitu, and vinyl/aryl halides and triflates as reagents. The reaction is general and offers a unique class of products in moderate to good yields for a wide range of substrates and electrophiles; for example

synthesis of highly substituted 1,3-dienes from the coupling of vinyl bromides with vinyl triflates is reported for the first time. The coupling is catalyzed by a combination of (5,5'-bis(trifluoromethyl)-2,2'-bipyridine)NiBr2 and (1,3-bis(diphenylphosphino)propane)PdCl2 in the presence of a zinc reductant. This method affords tetra- and penta-substituted 1,3-dienes that would otherwise be difficult

Rhodium(II) dicarboxylate complexes were discovered to catalyze the intramolecularamination of unactivated primary, secondary, or tertiary aliphatic C-H bonds using arylazides as the N-atom precursor. While a strong electron-withdrawing group on the nitrogen atom is typically required to achieve this reaction, we found that both electron-rich and electron-poor arylazides are efficient sources for
发现二羧酸铑 (II) 配合物使用芳基叠氮化物作为 N 原子前体催化未活化的伯、仲或叔脂肪族 CH 键的分子内胺化。虽然通常需要氮原子上的强吸电子基团来实现该反应,但我们发现富电子和缺电子芳基叠氮化物都是金属氮烯反应中间体的有效来源。
