Ru(II)-PNP complex demonstrated high activity in the anti-Markovnikov hydroalkylation of nonpolarized terminal alkenes via hydrazones. Hydrazone served as a carbanion equivalent to combine with the electrophilic alkene substrate upon activation by the ruthenium catalyst, forming a new C–C bond in a concerted pathway with N2 as the only theoretical byproduct. Experimental and computational studies suggested
结构明确的 Ru(II)-PNP 配合物在非极化末端烯烃通过腙的反马尔可夫尼科夫加氢烷基化中表现出高活性。腙充当碳负离子,在钌催化剂的活化下与亲电子烯烃底物结合,在协同途径中形成新的C-C键,N 2作为唯一的理论副产物。实验和计算研究表明存在推拉相互作用,激活烯烃进行腙加成,然后推断出其机理。
