Polycyclic Peroxides and Planar Nitrogens
1,6-diaza-3,4,8,9,12,13-hexaoxabicyclo[4.4.4] tetradecane (hexamethylene triperoxide diamine or HMTD) was found, by a single crystal x-ray study, to have planar bridgehead nitrogen atoms. In order to study this planarity, a synthesis was developed for HMTD analogs. Crystals structures were obtained...
