62% | With bis(di-tert-?butyl(4-?dimethylaminophenyl)?phosphine)?dichloropalladium(II); potassium tert-butylate; at 80 - 120℃; for 5h; | 1, 1mol of dichlorobromobenzene was added to 2.3mol diphenyl substituted carbazole compound, was added dropwise under nitrogen protection 1.1mol of L2PdCl2(L = AMPHOS, t-tert-butyl- (p-dimethylaminophenoxy) -phosphoric acid) and 2.5 mol of t-BuOK as a catalyst were added and the mixture was stirred well and then heated to 80 ° C for 2 hours and then heated The reaction was incubated at 120 ° C for 3 hours and then cooled to ambient temperature. 100 ml of water was added to precipitate a solid. The solid was washed with water and then with n-hexane and recrystallized from ethanol to give the pure intermediate A as a solid, yield 62percent. |
