Abstract
HPLC and NMR investigations of the kinetics of competitive binding by neighbouring side chains in his-metH demonstrate that at pH > 6 initia l S coordination is followed by slow isomerization to an imidazole-N-1 bound complex through a dinuclear intermediate [{Pt(dien)}(2)(his-met H-1 kappa N-1:2 kappa S)]4(+).
