Donor atom preferences in complexes of platinum and palladium with amino acids related molecules

Donor atom preferences in complexes of platinum and palladium with amino acids related molecules. Appleton, T. G. Coordination Chemistry Reviews, 166:313–359, 1997.
abstract bibtex

Amino acids present metal ion with a choice of potencial donor atoms. The preferences for a particular donor atom for palladiun(II) depends primarily on relative thermodynamic stabilities of the complexes formed, but for platinum thermodynamically less preferred complexes may be kinetically preferred, leading often to spontaneous conversion of a metastable complex into a themordynamically preferred linkage isomer. Sizes of potencial chelate rings onften play crucial role in determininf donor atom preferences. On a more subtle level, when geometric isomers are possible, with the same set of donor atoms bound to the metal, there may frequently be themodynamic or kinetic preferences for a particular isomer depending on trans influences and trans effects of other ligands. These preferences are most marked when the trans influences of some of theses ligands are very high, as in methylplatinum(IV) complexes. The review focuses on results obtained in the author's laboratory, and on relatec work of other groups.
