title: Directly fused highly substituted naphthalenes via Pd-catalyzed dehydrogenative annulation of N,N-dimethylaminomethyl ferrocene using a redox process with a substrate.
abstract: N,N-Dimethylaminomethyl ferrocenium could be generated in situ and served as a terminal oxidant for Pd-catalyzed directly dehydrogenative annulations of N,N-dimethylaminomethyl ferrocene and internal alkynes. This procedure utilized the redox activity of ferrocene and avoided adding an oxidant. A series of highly arylated naphthalenes functionalized by ferrocene were obtained in 53-81% yields.
