Substituent effect stabilization energies were estimated for sets of 27 para-substituted phenol derivatives, meta- and para-homodisubstituted benzene derivatives, trans-substituted ethenes, 4-substituted 1-hydroxy-1,3-cyclohexadienes and 1,4-homodisubstituted 1,3-cyclohexadienes based on the optimizations at the B3LYP/6-311+G** DFT level of theory. The following substituents were taken into account: C≡CH, C(CN)3, CF3, CH2NH2, CH3, CH=CH2, CHO, Cl, CN, COCH3, COCl, CONH2, COOCH3, COOH, F, NH2, NHCH3, N(CH3)2, NHOH, NO, NO2, OCH3, OH, Ph, H, SH, SO2CN. For hydroxyethenes and phenol derivatives the electron-acceptor substituents stabilize the systems, whereas the electron-donors lead to their destabilization. Both electron-acceptor and electron-donor substituents destabilize homodisubstituted ethene and meta- and para-homodisubstituted benzene species. The strongest destabilization is observed for derivatives of ethene, a weaker one for derivatives of cyclohexadiene and the weakest for benzene derivatives.

Dihydropyridine Derivatives

Half-wave potentials E1/2 of electrochemical oxidation of the title 1,4-dihydropyridine derivatives with the substituents N(CH3)2, OCH3, CH3, H, F, Cl, COOCH3, and CN have been measured on platinum rotating disc electrode in aqueous and anhydrous dimethylformamide, and apparent rate constants k2 of their oxidation with potassium ferricyanide have been measured in water at 298 K. The two quantities (E1/2 and k2) have been correlated both mutually and with empirical σp constants of the substituents. The found correlation relations have been discussed with respect to mechanism of the two transformations investigated.
