酰胺选择性催化C–N键裂解为增值胺产品是一种理想的但具有挑战性的转化。含有亚氨基二苄基基序的分子普遍存在于药物分子和功能材料中。在这里,我们建立了一种组合的KOH / BEt 3催化剂,用于将酰基-亚氨基二苄基衍生物(包括非杂环羧酰胺)进行脱氨基硼氢化成相应的胺。这种新颖的无过渡金属的方法也被用于氯米帕明和发光体的构建。

tertiary amides, including the biologically active aryl-phenazine carboxamides and the challenging non-heterocyclic carbonyl functions, using low-cost hydrosilane as a reducing reagent has been developed. The novel catalyst system exhibits high efficiency and exclusive selectivity, providing the desired amines in useful to excellent yields under mild conditions. Overall, this transitionmetal-free process

aromatic amines with aromatic aryl iodides. Full spectroscopic details are reported. Solutions of 1,3,5-tris(diarylamino)benzene derivatives in deuterated chloroform undergo hydrogen–deuterium exchange on the central ring and readily turn green owing to partial oxidation by traces of dissolved oxygen. The green colour is quenched by the addition of ascorbic acid. The solutions are more stable in chloroform

amides into value-added amine products is a desirable but challenging transformation. Molecules containing iminodibenzyl motifs are prevalent in pharmaceutical molecules and functional materials. Here we established a combined KOH/BEt3 catalyst for deaminative hydroboration of acyl-iminodibenzyl derivatives, including nonheterocyclic carboxamides, to the corresponding amines. This novel transition-metal-free
