1,4 addition of higher order Z vinyl cuprates to enones followed by triflate trapping results in the corresponding enol triflates, which can be coupled with terminal alkynes or with Z vinyl zinc chloride under Pd0 catalysis.
1,4在烯酮中添加较高级的Z乙烯基铜酸盐,然后进行三氟甲磺酸酯捕集,得到相应的烯醇三氟甲磺酸酯,可以在Pd 0催化下将其与末端炔烃或Z乙烯基氯化锌偶联。
