(DiMeIHeptCl)Pd, a hyper-branched N-aryl Pd NHC catalyst, has been shown to be efficient at performing amine arylation reactions in solvent-free (“melt”) conditions. The highly lipophilic environment of the alkyl chains flanking the Pd center serves as lubricant to allow the complex to navigate through the paste-like environment of these mixtures. The protocol can be used on a multi-gram scale to make
(DiMeIHept Cl )Pd是一种超支化 N-芳基 Pd NHC 催化剂,已被证明在无溶剂(“熔融”)条件下可有效地进行胺芳基化反应。Pd 中心侧翼烷基链的高度亲油环境充当润滑剂,使复合物能够通过这些混合物的糊状环境。该协议可用于多克规模,以制造各种苯胺衍生物,包括含有醇部分的底物。
