Optimised conditions are reported for Suzuki–Miyaura couplings between N-tosyl-2-bromo-benzylamines and -phenethylamines with vinylboronic acids, using pre-mixes of catalyst, ligand and base, leading to the corresponding 2-tosylaminomethyl- and 2-tosylaminoethyl-styrenes in generally excellent yields, using microwave excitation at 100 °C.
据报道,使用催化剂,配体和碱的预混物,使N-甲苯磺酰基-2-溴苄胺和-苯乙胺与乙烯基硼酸之间的Suzuki-Miyaura偶联反应的优化条件,产生了相应的2-甲苯磺酰基氨基甲基和2-甲苯磺酰基氨基乙基-使用100°C的微波激发,苯乙烯通常具有优异的收率。
