✦ Synopsis


According to quantum chemical calculations at an ab initio diphosphete structures: π donors at phosphorus strongly elongate the P-P bond while electronegative substituents at level parent 1,2-diphosphete is slightly more stable than its corresponding 1,4-diphosphabutadiene structural isomer.

phosphorus increase the interflap angle of the fourmembered ring systems, bringing an envelope conformation The quantum chemical calculations indicate that substituents at phosphorus and to a much less extent at carbon exert to the fore. The lengthening of the P-P bond gives rise to a Möbius-type delocalization within the ring moiety. strong influences on the equilibrium geometries of 1,2-

## Abstract The bridged homotropilidines have been of interest for decades because their molecules offer the potential for homoaromaticity. Although many of these have been shown not to be homoaromatic, the energy differences of the delocalized (homoaromatic) forms and the localized (nonhomoaromati

The dication NH 2q has been studied by state-of-the-art quantum 5 chemical techniques. NH 2q is a square-based pyramid with C symmetry. The apical H 5 4 v is bonded to N with a 2-electron covalent bond, while the other H atoms are bonded to N through degenerate 2-electron 3-center bonds. No other lo
