| Abstract: | Cyclooctatetraenes, including dibenzocyclooctatetraenes, are structurally interesting compounds and are widely used in many areas. Therefore, the development of synthetic methods for such compounds has long been attractive. In this work, a Pd-catalyzed coupling reaction between alkenylbromides and arylbromides has been realized. Multi-substituted 1,4-dibromo-1,3-butadienes and o-bromo-2-(2-bromovinyl)benzenes underwent a Pd-catalyzed cyclodimerization reaction to afford the corresponding multi-substituted cyclooctatetraenes and dibenzoa,e] cyclooctatetraenes, respectively, in high yields and with excellent regioselectivity. |
