Structural effects in solvolytic reactions; carbon-13 NMR studies of carbocations(†): Effect of increasing electron demand on the carbon-13 NMR shifts in substituted tert-cumyl and 1-aryl-1-cyclopentyl carbocations—correlation of the data by a new set of substituent constants, σ(C+)

The cationic carbon substituent chemical shifts (ΔδC(+)) for nine representative meta-substituted tert-cumyl carbocations are correlated satisfactorily by the σ(m)(+) substituent constants (slope ρ+ = -18.18, correlation coefficient r = 0.990). However, the substituent chemical shifts (ΔδC(+)) for t...
