A selective ruthenium-catalyzed water–gas shift/hydroformylation of internal olefins and olefin mixtures is reported. This novel domino reaction takes place through a catalytic water–gas shift reaction, subsequent olefin isomerization, followed by hydroformylation and reductive amination. Key to the success for the efficient one-pot process is the use of a specific 2-phosphino-substituted imidazole
据报道,选择性钌催化的内部烯烃和烯烃混合物的水煤气变换/加氢甲酰化反应。这种新颖的多米诺骨牌反应是通过催化水煤气变换反应,随后的烯烃异构化,然后进行加氢甲酰化和还原胺化而发生的。有效一锅法成功的关键是使用特定的2-膦基取代的咪唑配体和十二碳三钌作为前催化剂。工业上重要的内烯烃通常与各种胺反应生成相应的叔胺,且收率和选择性都很好。该反应顺序构成了合成线性胺的经济上有吸引力且对环境有利的方法。
