Metallkomplexe mit biologisch wichtigen Liganden, CLI [1]. Metallorganische Komplexe mit R-3-(3-Pyridyl)alaninat
Abstract
<jats:p>Reactions of chloro bridged complexes with R-3-(3-pyridyl)alanine afford the chelate complexes L<jats:sub>n</jats:sub>M[NH<jats:sub>2</jats:sub>CH(CO<jats:sub>2</jats:sub>)CH<jats:sub>2</jats:sub>C<jats:sub>5</jats:sub>H<jats:sub>4</jats:sub>NH<jats:sup>+</jats:sup>]Cl<jats:sup>−</jats:sup> (L<jats:sub>n</jats:sub>M = Ph<jats:sub>3</jats:sub>P(Cl)Pd, (tol<jats:sub>3</jats:sub>P)(Cl)Pd, (Ph-pyridyl)<jats:sub>2</jats:sub>Ir, Cp٭(Cl)Rh, Cp٭(Cl)Ir, (p-Cymol)(Cl)Ru) with protonated pyridine substituents. An analogous Cp٭Rh complex with 3-(2-pyridyl)alaninate was also obtained. Addition of base (NaOMe) to these complexes gives dimeric and trimeric complexes with coordination of the pyridine N atom.</jats:p>
