Applications of 1,3,5-hexatriene derivatives in atom-economic cobalt-catalyzed transformations, such as the Diels–Alder reaction with alkynes, the 1,4-hydrovinylation reaction with terminal alkenes, and the 1,4-hydrohexatrienylation reaction, are investigated. In all cases, regioselective transformations were found to generate cyclic derivatives such as stilbenes or acyclic products with a high control
1,3,5-己三烯衍生物在原子经济的钴催化转化中的应用,例如与炔烃的狄尔斯-阿尔德反应,与末端烯烃的1,4-氢乙烯基化反应以及1,4-氢己三烯化反应调查。在所有情况下,都发现区域选择性转化可产生环状衍生物,例如对苯二甲酸酯或无环产物,这些化合物可高度控制由1,4-氢乙烯基化过程衍生的跳过的三烯中的双键几何形状,或迄今为止迄今为止空前的1中产生的四烯1。 ,4-氢己三烯化反应。
