Whereas the reaction of simple octa-1,7-diynes is fruitless, those bearing ester groups on the terminal positions react with alkynols in the presence of stoichiometric amounts of a nickel(0) reagent derived from NiCl2(PPh3)2 and BunLi to give tetralin lactones in moderate to good yields.
简单的八-1,7-二炔反应没有结果,而末端位置带有酯基的八-1,7-二炔与炔醇在一定量的由 NiCl2(PPh3)2 和 BunLi 制得的
镍(0)试剂存在下发生反应,生成四氢
萘内酯,产率为中等到良好。
