In recent years, H2 activation at non‐transition‐metal centers has met with increasing attention. Here, a system in which H2 is activated and transferred to aldimines and ketimines using substoichiometric amounts of lithium bis(trimethylsilyl)amide is reported. Notably, the reaction tolerates the presence of acidic protons in the α‐position. Mechanistic investigations indicated that the reaction proceeds
近年来,非过渡金属中心的H 2活化受到越来越多的关注。在此,报道了使用亚化学计量的双(三甲基甲硅烷基)氨基锂将H 2活化并转移至醛亚胺和酮亚胺的系统。值得注意的是,该反应可耐受α位酸性质子的存在。机理研究表明,反应通过氢化锂中间体作为实际的还原剂进行。
