Fe, Pd, Cu), the aluminum co-catalyst (MMAO, Et2AlCl, or EtAlCl2) or the substituents of the tris(iminophosphorane) ligand (R = Me, Ph; R′ = cyclopentyl, Ph). Structural modifications of the organometallic complexes, either at the metal center or within the tripodal ligand, however, had a significant impact on the oligomer distribution obtained. In particular, Pd-based catalyst (PhC(CH2NPPh3)3)PdCl2
通式RC的七过渡金属配合物(CH 2 NPR ' 3)3)MX 2 RC(CH2NPR'3)3)MX 2基于新的三足膦亚胺配位体进行了研究作为引发剂对乙烯在低聚使用高通量技术的铝助催化剂的存在。在所有情况下,乙烯的消耗量都达到峰值。30°C,并且不受金属(M = Ni,Fe,Pd,Cu),铝助催化剂(MMAO,Et 2 AlCl或EtAlCl 2)或三(亚氨基正膦)配体的取代基(R = Me,Ph; R'=环戊基,Ph)。然而,有机金属配合物在金属中心或三脚架配体内部的结构修饰对所得的低聚物分布具有重大影响。特别地,基于Pd的催化剂(PhC(CH 2 NPPh 3)3)PdCl 2对己烯形成表现出优异的选择性。
