A simple and efficient Mn-catalyzed acylation of amines is achieved using both acyl and alkoxy functions of unactivated esters with the liberation of molecular hydrogen as a sole byproduct. The present protocol provides an atom-economical and sustainable route for the synthesis of amides from esters by employing an earth-abundant manganese salt and inexpensive phosphine-free tridentate ligand.

hydroxyapatite-supported Pd nanoparticle catalyst (Pd/HAP), various primary anilines can be selectively synthesized from cyclohexanones via acceptorless dehydrogenative aromatization. The strong nucleophilicity of N2H4 and the stability of the hydrazone intermediates can effectively suppress the formation of the undesired secondary aniline byproducts.
通过在羟基磷灰石负载的 Pd 纳米颗粒催化剂 (Pd/HAP) 存在下利用肼 (N 2 H 4 ) 作为氮源,可以通过无受体脱氢芳构化从环己酮选择性地合成各种伯苯胺。N 2 H 4的强亲核性和腙中间体的稳定性可以有效抑制不需要的次级苯胺副产物的形成。
