Abstract
The PM3 procedure was applied to analyze charge and spin density distributi on in radical cations of 1-X-tricyclo[4.1.0.0(2,7)]heptanes (X' = H, CO2Me, SMe; structure A) and products of their thermal isomerization with complet ely broken central bicyclobutane C-1-C-7 bond (B), broken peripheral C-1-C- 2 (C) and C-2-C-7 bonds (D), and also 1,3-cycloheptadiene structure (E). Th e general trend is successive increase in the relative stability of radical cations in going from structure A to E.
