The cycloaddition reaction between conjugated diynes and 1,3,5-cyclooctatriene in the presence of the catalyst Co(acac)2/dppe/Zn/ZnI2, led to the selective formation of tricyclo[4.2.2.02,5]deca-7,9-diene derivatives in 72–85% yield.
在催化剂Co(acac)2 / dppe / Zn / ZnI 2的存在下,共轭二炔与1,3,5-环辛三烯之间的环加成反应导致选择性形成三环[4.2.2.0 2,5 ] deca- 7,9-二烯衍生物,产率为72–85%。
