An organoindium generated from the reaction of indium with allenylmethyl bromide is an efficient nucleophile in Pd-catalyzed cross-couplings, producing 1,3-butadienes; cross-couplings followed by [4 + 2] cycloadditions gave six-membered carbocycles in a one-pot process.
由铟与烯丙基甲基溴反应生成的有机铟是一种高效的亲核试剂,能在钯催化的交叉偶联反应中生成1,3-丁二烯;交叉偶联反应后再进行[4 + 2]环加成反应,能够在一步法中生成六元碳环化合物。
