Multicenter bonding in carbocations with tetracoordinate protons
The nature of the bonding in a set of nonclassical carbocations with tetracoordinated protons "sandwiched" between two C=C pi bonds was scrutinized using the new computational methodology of generalized population analysis. The results of this theoretical analysis strongly corroborate the conclusions of a previous study in which the occurrence of delocalized 5-center 4-electron (5c-4e) bonding in the C-C-H-C-C fragments of such cations was anticipated.
