The nickel N,N,N-pincer complex 2 was demonstrated to effectively catalyze the cross-coupling of arylsulfamates with arylzincchlorides under mild conditions. The reaction is suitable for a wide range of substrates, and tolerates various functional groups.
showed efficient catalytic activity toward the Suzuki–Miyauracoupling of aryl sulfamates with arylboronic acids or potassium phenyltrifluoroborate, giving the expected coupling products in good to high yields. It should be noted that this is the first example so far of the phosphine-free, NHC–Pd(II) complexes catalyzed Suzuki–Miyauracoupling of aryl sulfamates with arylboronic acids.
The nickel‐catalyzed deoxygenative deuteration of aryl/heteroaryl sulfamates has been developed, and the effective incorporation of deuterium into a variety of aromatic compounds was achieved with sufficient catalytic efficiency and high deuteration degree. This process tolerated reducible functional moieties and heterocyclic structures. Additionally, a double introduction of deuterium also successfully
