title: Studies on the reaction of benzo[x]quinoline N-oxides (X = f, h, and g) with methylsulfinyl carbanion using the semi-empirical molecular orbital method. Liberation of the N-oxide group.
abstract: The mechanism of the liberation reaction of the N-oxide group has been studied and compared with the methylation reaction using a semi-empirical molecular orbital PM3 method. By comparing the calculated values of Gibbs free energy of activation, we can determine whether a liberation reaction or methylation reaction occurs.
