摘要

Ion-pair coordination of phosphoric acid diesters with positively charged guanidines may cause large rate accelerations in substitution reactions. Here we present a comparative study on the catalytical influence of several mono-bis-and tris (guanidines) and of other cationic compounds. Large rate effects occur if 1, 3-bis (aminomethyl) benzene or 1, 2-ethy- RNA cleaving agents. lenediamine are used as spacers. Further acceleration can be ...
