The mixing of equal volumes of 0.2 mmol dm-3 1-benzylnicotinamide ion and 2 mmol dm-3 cyanide ion results in the immediate formation of a transient absorption band at 375 nm which can be ascribed to a charge-transfer complex.This com

The rate constants k2 and equilibrium constants K=k2/k-2 of the title process (A) have been measured in aqueous solutions of eight quaternary salts of nicotinamide I (R= p-XC6H4CH2) at 298 K.The substituent effects of X= CH3O, CH3, H, F, Cl, COOCH3, CN, and NO2 exhibiting the Hammett dependence have been correlated with half-wave potentials of reduction of the depolarizers I, and the correlation results have been discussed with respect to mechanism of the reaction (A).
