Rapid and Highly Selective Cleavage of Ribonucleoside 2′,3′‐Cyclic Monophosphates by Dinuclear CuII Complexes

Two characteristics that never before appeared together are combined in complexes 1 and 2, which show high activity and high selectivity in the hydrolysis of cyclic nucleoside 2′,3′-monophosphates as model compounds for RNA. In the case of 1 the regioselectivity is exceptional, and, in the case of 2, the base selectivity.
