symmetric 1,3-diynes to cyclohepta-1,3,5-triene under the action of the three-component catalytic system Co(acac)2(dppe)/Zn/ZnI2 was realized for the first time. Previously unreported disubstituted bicyclo[4.2.1]nona-2,4,7-trienes were obtained in high yields (78–98%) and characterized.
在三组分催化体系Co(acac) 2 (dppe)/Zn/ZnI 2作用下,对称1,3-二炔与环庚-1,3,5-
三烯的[6π+2π]-环加成催化反应为第一次意识到。以前未报道的双环[4.2.1]壬二烯-2,4,7-
三烯以高产率(78-98%)获得并进行了表征。
