A direct reductive amination protocol for aldehydes/ketones using bis(triphenylphosphine) copper(I) tetrahydroborate as a novel reducing agent in the presence of sulfamic acid has been developed. The reagent chemoselectively reduces the imine moiety and does not affect other reducible functionalities such as chloro, nitro, cyano and methoxy.

Direct reductive amination of aliphatic, aromatic and heterocyclic carbonyl compounds with primary/secondary amines is reported with water-soluble FeII/EDTA complex as a catalystusing low-pressure molecular hydrogen in a biphasic media. The catalyst is highly selective, recyclable and is an excellent replacement for expensive noble metal catalysts or stoichiometric reducing agents.
据报道,水溶性Fe II / EDTA络合物作为催化剂,使用低压分子氢在双相介质中,将伯,仲胺直接与脂肪族,芳香族和杂环羰基化合物进行还原性胺化反应。该催化剂具有高选择性,可回收利用,是昂贵的贵金属催化剂或化学计量还原剂的理想替代品。

A simple and efficient method for the preparation of secondary N-alkylarylamines via reductive amination of ketones with primary aromatic amines using activated zinc/acetic acid is described. It requires only equimolar amounts of the starting compounds and affords good yields of the corresponding amines (50-90%). It is not applicable to aldehydes nor aliphatic amines.
