A highly regioselective functionalization of 7-bromofluorene-2-carbaldehydes, potent organic chromophores, in position C3 using a mild ortho-metallation strategy (DoM) with TMPMgCl·LiCl has been developed. This approach allows the preparation of highly functionalized fluorene derivatives by conversion of the in situ generated metalated species with various electrophiles giving a fast access to novel
已经开发了使用TMPMgCl·LiCl的温和邻位金属化策略(D o M)在位置C3上对7-溴芴-2-甲醛(有效的有机发色团)进行高度区域选择性的官能化反应。这种方法可以通过将原位生成的金属化物种与各种亲电试剂进行转化来制备高度官能化的芴衍生物,从而可以快速获得新型有机磷光染料。
