The present invention relates to a method of reacting starting materials with an activating group, namely alkanes carrying a leaving group and/or olefins, with carbon dioxide under transition metal catalysis to give carboxyl group-containing products. It is a special feature of the method of the present invention that the carboxylation predominantly takes place at a preferred position of the molecule irrespective of the position of the activating group. The carboxylation position is either an aliphatic terminus of the molecule or it is a carbon atom adjacent to a carbon carrying an electron withdrawing group. The course of the reaction can be controlled by appropriately choosing the reaction conditions to yield the desired regioisomer.
本发明涉及一种方法,通过在过渡金属催化作用下,将带有离去基团和/或烯烃的烷烃与二氧化碳反应,以得到含有羧基的产物。本发明的方法的一个特殊特点是,羧化反应主要发生在分子的一个优选位置,而不受活化基团位置的影响。羧化位置要么是分子的脂肪末端,要么是邻近带有电子提取基团的碳原子。通过适当选择反应条件,可以控制反应的过程,以产生所需的位置异构体。
