Efficient C–N and C–Ocouplingreactions of aryl halides with amines and alcohols have been developed by using the strategy of heterogeneous visible light photoredox and nickel dual catalysis. Obviously, the joint use of inexpensive and bench-stable CdS and nickel salts, together with mild reaction conditions, makes these two transformations attractive for the synthetic community. This heterogeneous

Hydrogenation of C=C bond and reductive amination are important transformations utilized in chemistry. An environmentally friendly, efficient, and facile one-pottransferhydrogenation of C=C bond of enones and reductive amination of C=N bond of imines are reported using iridium complex as catalysts and formic acid as hydrogen source in aqueous medium. In this catalytic system, a wide range of α-alkylated
C = C键的加氢和还原胺化是化学中重要的转变。据报道,使用铱络合物作为催化剂,甲酸为氢源,在水性介质中,对烯酮的C = C键进行环境友好,高效,便捷的一锅转移加氢和亚胺的C = N键还原胺化。在该催化体系中,通过C = C键的一锅转移加氢和还原胺化,可以以优异的收率获得各种α-烷基胺。该协议的实际应用以克级转换为特征。
