catalytic system consisting of NiSO4 and K2S2O8 has been found to be effective for the oxidation of secondary amines to imines. 1,2,3,4-Tetrahydroisoquinoline was oxidized to 3,4-dihydroisoquinoline as the main product with a small amount of isoquinoline. N-Benzylaniline gave N-benzylideneaniline and a N-N coupling dimer.
已发现由 NiSO4 和 K2S2O8 组成的催化体系可有效将仲胺氧化为亚胺。1,2,3,4-四氢异喹啉与少量异喹啉氧化成3,4-二氢异喹啉为主产物。N-苄基苯胺得到N-苄叉苯胺和NN偶联二聚体。
