AlMe3-promoted oxidative cyclization of eta2-alkene and eta2-ketone on nickel(0). Observation of intermediate in methyl transfer process.
AlMe3 can promote the oxidative cyclization of eta2-alkene and eta2-ketone on nickel(0) to give an intriguing nickel-aluminum dinuclear complex having a bridging methyl group, which might be an intermediate for the nickel-catalyzed cycloisomerization of o-allylacetophenone or o-allylbenzophenone.
