Route of Synthesis (ROS)
| Conditions | Yield |
| With palladium diacetate In tert-butyl alcohol at 20℃; for 12h; Experimental Procedure General procedure for cross-coupling of arenediazoniums General procedure: To a mixture of arenediazonium tetrafluoroborates (1.2mmol) and diarylborinic acids (0.5mmol) was added 4mL tert-butanol solution containing 0.67mg (0.3mol%) Pd(OAc)2 prepared prior to use. The mixture was stirred at room temperature for a given time or monitored by TLC until the starting materials were completely consumed. The reaction mixture was diluted with CH2Cl2 (15 mL), followed by washing with H2O (2×10mL). The organic layer was dried over Na2SO4, filtered, and evaporated under reduced pressure to give crude product, which was purified by column chromatography on silica gel with petroleum ether/ethyl acetate as eluent. | 95% |
