The reduction of substituted benzylidene malonic diesters by 1-benzyl-1,4-dihydronicotinamide (BNAH) is catalyzed by magnesium perchlorate.Kinetic isotope effects studies show that the C(4)-H bond cleavage in BNAH is involved in the rate determining step.Spectroscopic investigations have revealed that the ternary complex is formed in the ground state while complexation of substrate with magnesium ion is rate enhancing.
