1-Phenyltricyclo[4.1.0.02.7]heptane reacted with N-bromo-, N-chloro-, and N-iodosuccinimides and with mercury(II) acetate in the presence of sodium azide as external nucleophile to give conjugate addition products to the central C1–C7 bicyclobutane bond with a norpinane structure, where the azido group and the phenyl were attached to the same carbon atom (C6). The bromo- and chloroazidation showed
