Nucleophilic attack on π-etheneplatinum(II) complexes: cis-isomers
Abstract
1
H-n.m.r. spectroscopy has been used to demonstrate that nucleophilic attack by pyridine on the CC bond in cis-dichloro(π-ethene)(pyridine)platinum(II) readily leads to the formation of the σ-bonded complex, cis-dichloro(pyridine)(2-pyridinioethanide)platinum(II), which is much more stable than the corresponding trans isomer.
