苯酚，烯醇，唑類，炔及其他C-, O-和N-負離子和三價或五價有機鉍試劑作用進行芳基化的反應。此類反應在中性，酸性或堿性條件下都可以進行。N芳基化可以在醋酸銅存在下，與Ar3Bi（可以由ArLi或ArMgX和三氯化鉍反應制得）反應實現(xiàn)，醇類的O芳基化可以在醋酸銅存在下和Ar4BiF反應得到。[5][17]

反應實例
1-Phenyl-2-naphthol (2). To a stirred solution of Ph3BiCl2 (550 mg, 1.07 mmol) and 2-naphthol 1 (144 mg, 1 mmol) in THF (1 M) at 20 ℃ under Ar was added tetramethyl-2-t-butylguanidine (TMBG, 500 mg, 0.11 mmol). After 5 h stirring, usual workup and chromatography (silica gel, Et2O:hexane 1:4) 198 mg of 2 (90%) was isolated.
