Push-pull and bifunctional acid-base catalysis

5 Push-pull and bifunctional acid-base catalysis [Pg.307]

In the 1950s, the push-pull mechanism whereby a proton is donated by one centre and received at another was considered as a major contributor to enzyme catalysis and to give rise to third-order terms in non-enzymic reactions. Third-order terms were observed in organic solvents but in water they are of minor importance because of the solvating power of this solvent for ions and polar centres. [Pg.307]
