Abstract
Addition of terpyridine to (TMEDA)Ni(CH3)2 results in the high-yield formation of (terpyridyl)NiMe (3). This NiI organometallic complex was found to be capable of transferring its methyl group to iodocyclohexane to produce methylcyclohexane in high yield. Compound 3 can also serve as an initiator for the catalytic cross-coupling of alkyl electrophiles performed under Negishi-like conditions.
摘要
将三联吡啶添加到(TMEDA)Ni(CH₃)₂中会高产率地生成(三联吡啶基)NiMe(3)。发现这种NiI有机金属配合物能够将其甲基转移到碘代环己烷上，以高产率生成甲基环己烷。化合物3还可以作为在类似根岸条件下进行的烷基亲电试剂催化交叉偶联的引发剂。
