    Abstract

    The title compound was synthesized by thermal reaction of 3-phosphoranylidene-amino-1,6-methano[10]annulene with 2-chlorotropone in a single step. The examination of 1H NMR spectrum revealed that there is little contribution of peripheral 18-π electron conjugation, but it is rather composed of 1-azaazulene and methano[10]annulene moieties.
