Fast water exchange on a Pt(II) center: variable temperature and pressure O-17 NMR study at 14.1 tesla of the ionic arylplatinum species [Pt{C6H3(CH2NMe2)(2)-2,6}(OH2)](+)(OSO2CF3)(-)

摘要

The water-soluble ionic aryl platinum species [Pt{C6H3(CH2NMe2)-2,6}(OH2)](+) undergoes water exchange at a rate 10(7) times faster than the coordination complex [Pt(OH2)(4)](2+): a clear-cut example of the trans effect of the C-banded organic group. Lineshape analysis of high pressure O-17 NMR data acquired in a 14.1 tesla magnet are indicative for an associative mode of activation for this water exchange. (C) 1998 Elsevier Science S.A.
