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

N-(1-Oxy-pyridin-2-ylmethyl)oxalamicacid was identified as efficientligand for CuI-catalyzed amination of aryl halides at roomtemperature. In our catalytic system, N-arylation of cyclic secondary amines, primary amines, amino acids, and ammonia proceeded with moderate to excellent yields and high functional group tolerance.

A series of robust N‐heterocyclic carbene palladacycles have been successfully developed. These showed high catalytic activity and selectivity toward the challenging amination of N‐heteroaryl chlorides. Different primary and secondary amines were fully compatible with this catalytic system. Remarkably, no double amination products could be detected when primary amines were utilized in our catalytic
