A protocol for the hydrocarboxylation of disubstituted alkenes and terminal alkynes providing access to different secondary carboxylic acids and malonic acid derivatives has been developed. This methodology relies on an initial hydroboration using 9-BBN followed by carboxylation with carbon dioxide in the presence of a copper catalyst and the additive, cesium fluoride. Different cyclohexene, styrene
已经开发了用于双取代的烯烃和末端炔烃的加氢羧化的方案,其提供了获得不同的仲羧酸和丙二酸衍生物的途径。该方法依赖于首先使用9-BBN进行硼氢化,然后在铜催化剂和添加剂氟化铯的存在下用二氧化碳进行羧化。可以利用不同的环己烯,苯乙烯和二苯乙烯衍生物,并且炔可以良好的产率转化为它们相应的二羧酸。最后,使用开发的方法将六种不同的萜类化合物羧化。
