  1,8-Bis(diphenylmethylium)naphthalenediyl Dication as an Organic Oxidant:  Synthesis of Benzidines via Self-Coupling of N,N-Dialkylanilines

  摘要：

  1,8-Bis(diphenylmethylium)naphthalenediyl dications promoted oxidative coupling of various N,N-dialkylanilines to afford the corresponding para-coupled bisanilines, benzidines, in good to excellent yield. The dications were readily prepared from a cyclic ether precursor, derived from 1,8-dibromonaphthalene, via deoxygenation with a silylating reagent in 1,1,1,3,3,3-hexafluoro-2-propanol under anhydrous conditions.

  Naphthalene-1,8-diylbis(diphenylmethylium) as an Organic Two-Electron Oxidant:  Benzidine Synthesis via Oxidative Self-Coupling of N,N-Dialkylanilines

  摘要：

  Naphthalene-1,8-diylbis(diphenylmethylium) exhibits a unique electron-transfer reduction behavior due to the close proximity of the two triarylmethyl cations, which form a C-C bond while accepting two electrons, leading to 1,1,2,2-tetraphenylacenaphthene. The preparation of the dication was readily accomplished under anhydrous conditions starting from a cyclic bis(triarylmethyl) ether, derived from 1,8-dibromonaphthalene. The process proceeded via deoxygenation accompanying the formation of a disiloxane on treatment with a silylating agent (Me3SiClO4 or Me3SiOTf) in 1,1,1,3,3,3-hexafluoropropan-2-ol. The dication was successfully employed for oxidative coupling of N, N-dialkylanilines at the paraposition to afford the corresponding benzidines in good to excellent yield.
