Sensitive functional groups such as COR, CHO, or CH2OH can be present in benzylic indium reagents prepared by the direct insertion of indium in the presence of LiCl. These reagents undergo palladium‐catalyzed cross‐coupling reactions in the presence of a protic cosolvent after activation with iPrMgCl⋅LiCl (see scheme). Remarkable chemoselectivities are achieved by using various electrophiles containing
敏感的官能团(例如COR,CHO或CH 2 OH)可以存在于通过在LiCl存在下直接插入
铟而制备的苄基
铟试剂中。这些试剂经历在质子共溶剂的存在下进行
钯催化的交叉偶联反应活化后与我PrMgCl⋅LiCl(参见方案)。通过使用各种含有NH或OH基团的亲电试剂,可获得显着的
