“…1 Therefore, many efforts have been devoted to developing approaches for preparing 1,7-octadienes; however, there only exist quite a few methods such as the catalytic decarboxylation of alkanedioic acid, dehydration of alkanediol, metathesis of cyclohexene with ethylene, Grignard reaction of halogenated hydrocarbons, or reductive coupling reaction of halogenated alkenes (Scheme 1A). 2 Apparently, all these synthetic methods are currently the most reliable methods to access simple terminal 1,7-octadienes due to the low cost of raw materials, convenient post-treatment and less pollution, but for the synthesis of complex terminal 1,7-octadienes containing an all-carbon quaternary center there are great challenges. Given the importance of terminal 1,7-octadienes in materials science, the exploration of an alternative general and practical protocol for constructing complex terminal 1,7-octadienes with an all-carbon quaternary center from simple and readily available raw materials is highly desirable.…”
