✦ Synopsis

R. D. Brown (1) has shown that molecular-orbital calculations of localleatlon energies satlsfaotorlly reproduoe the observed partial rate factors for substitution of pyrldlne by phenyl radicals. Similar calculations for the pyrldlnlum Ion (2) suggest greatly enhanced reactivity at the P-position
