Useful intermediates: Addition of silyl‐substituted chloroalkynes to terminal alkynes, namely chloroalkynylation, proceeds under palladium catalysis to afford (Z)‐1‐chloro‐1,3‐enynes (see scheme). The carbon–chlorine bond of the adducts is easily convertible to a carbon–carbon bond by using palladium‐catalyzed cross‐coupling reactions to provide a variety of 1,3‐enynes.
有用的中间体:在钯催化下,将甲硅烷基取代的氯炔烃加到末端炔烃上,即进行氯炔基化反应,得到(Z)-1-氯-1,3-烯炔(见方案)。通过使用钯催化的交叉偶联反应可提供多种1,3-炔烃,加合物的碳-氯键很容易转化为碳-碳键。
