Results Pseudo-first-order rate constanta (how) for the reaction of l-benzyl-1, 4- dihydronicotinamide (5) with the 2-methylisoquinolinium cation (4 (X= H)) and its 4-bromo derivative (4 (X= Br)) as a function of isoquinolinium cation concentration display kinetic saturation effects. Double-reciprocal plots of these data are linear (Figure 1) and may be characterized by slope and ordinate intercept
