An efficient heterogeneous catalytic system based on NiGa layered double oxide (Ni3Ga-LDO) for the C—N coupling between isochroman and primary arylamines has been described. Various primary arylamines were tolerated by the catalytic system, and good to excellent yields for the corresponding coupled products could be obtained. The results indicated that Ni species played the key role in the oxidative cross-coupling process, and the catalyst had good catalytical and structural stability. The protocol provides an effective alternative approach to construct C—N bond.

Key words: oxidative coupling, isochroman, primary arylamine, NiGa layered double oxide, C—N construction
