prepared by directed lithiation of 1-N,N-dimethylnaphthalene, followed by reaction borate esters. Both diisopropyl and pincacol ester derivatives of the resulting boronates were prepared, together with a novel boroxine which shows novel N–B interactions in the crystal structure. The corresponding dimethyl-[8-(difluoroborolyl)-naphthalen-1-yl]-amine was directly accessed from the boroxine by reaction with
