(Cyclopropylidenecyclohexyl)benzene derivatives, a kind of methylenecyclopropane (MCP) containing a cyclohexyl group, can undergo an interesting tandem intramolecular C−H and C−C bond activation through dehydrogenated rearrangement in the presence of AuPPh3Cl/AgOTf by transferring three hydrogen atoms from cyclohexane to cyclopropane, affording the corresponding biaryl derivatives in moderate to good
(环亚丙基环己基)苯衍生物是一种含环己基的亚甲基环丙烷(MCP),在AuPPh 3 Cl / AgOTf的存在下,通过转移三个氢原子,可以通过脱氢重排进行有趣的串联分子内CH和C-C键活化从环己烷到环丙烷,从中到高收率得到相应的联芳基衍生物。还通过氘标记实验和DFT计算仔细研究了反应机理。
