The 1H and 13C NMR spectra of a series of 1, 3-di-tert-butyl-1, 3-diazacyclohexanes 6, and of 1, 5-diazabicyclo [3.2. 1] octanes 7, have been investigated in an attempt to find evidence regarding a stereoelectronic interaction of the non-bonding electron pairs on nitrogen or of the C–N bonding electron pairs in the ring, with the axial and equatorial CH bonds of the α- or β-methylene groups. In 6, the orbital carrying the non-bonding electron pair lies ...
