Magnesium vinyl-copper derivatives, obtained by carbocupration of terminal alkynes, couple with 1-halo-1-alkenes, in the presence of Pd(PPh3)4 catalyst, to afford polysubstituted conjugated dienes in high yield and excellent stereoisomeric purity.
在Pd(PPh 3)4催化剂存在下,通过将末端炔烃与1-卤代-1-烯烃偶合进行碳化制得的乙烯基乙烯基铜铜衍生物,可以高收率和优异的立体异构纯度提供多取代的共轭二烯。
