실험 절차

In another embodiment, there is provided a method for forming an arylamine, comprising adding 4-bromobiphenyl and diphenylamine in toluene into a continuous plug flow reactor, the continuous plug flow reactor further comprising continuously reacting the 4-bromobiphenyl and the diphenylamine in the toluene in a presence of a base and a palladium catalyst under Buchwald conditions in the continuous plug flow reactor, adding a phosphonium-based ionic liquid with tri-t-butylphospine to the 4-bromobiphenyl and the diphenylamine in the continuous plug flow reactor, continuously reacting the 4-bromobiphenyl and the diphenylamine in the toluene and the phosphonium-based ionic liquid with the tri-t-butylphospine in the presence of the base and the palladium catalyst under Buchwald conditions in the continuous plug flow reactor until N,N-diphenyl-4-biphenylamine is produced, and collecting the N,N-diphenyl-4-biphenylamine.
