Kinetics of reactions in heterocycles. Part XV. Reactions of 2-, 6-, or 8-methylthio-1-, -3-, -7-, or -9-methylpurines and related compounds with methoxide ions in methanol

Abstract

Kinetics have been measured and Arrhenius parameters calculated for the reactions of some 2-, 6-, or 8-methylthio1-, -3-,-7-, or -9-methylpurines, 2-methylthio-1 (and 3)-methyl-1,3,5-triazaindene, and 2-methylsulphonyl-1-methylbenzimidazole with methoxide ions in methanol. The positional order of reactivity in the 1-methylpurines was 6 > 2 > 8 and in the 3-methylpurines 6 > 8.
