A recyclable rhodium polyether diphosphinite complex anchored in polyethylene glycol [RhPEGD] was studied for hydroaminomethylation of various olefins with primary and secondary amines. The protocol was optimized with respect to various reaction parameters and the general applicability of catalyst for hydroaminomethylation of different functionalized olefins with corresponding amines was investigated
研究了固定在聚乙二醇[RhPEGD]中的可循环利用的铑聚醚二亚膦酸酯络合物,用于各种烯烃与伯胺和仲胺的加氢氨基甲基化反应。该协议针对各种反应参数进行了优化,并研究了催化剂用于不同官能化烯烃与相应胺进行氢氨甲基化反应的一般适用性。在反应过程中,催化剂可溶于反应物/产物中,而在反应完成时可通过添加反溶剂以双相形式从反应介质中定量分离出来。该催化剂表现出显着的活性,随后被循环使用多达五个连续循环。
