Winkelhaus D, Neumann B, Mitzel NW. An Intramolecular Boron Nitrogen Lewis Acid Base Pair on a Rigid Naphthyl Backbone. ZEITSCHRIFT FUER NATURFORSCHUNG SECTION B-A JOURNAL OF CHEMICAL SCIENCES. 2012;67b(6):589-593.The reaction of (C6F5)(2)BCl with 8-lithio-N,N-dimethyl-1-naphthylamine (1) afforded the five-membered ring system 8-bis(pentafluorophenyl)boryl-N,N-dimethyl-1-naphthylamine (2) with an intramolecular dative B-N bond. The compound was characterised by elemental analysis, NMR spectroscopy and single-crystal X-ray diffraction
