- 論文の詳細を見る
New complexes of <I>N</I>-allylpyrazole(L) with Pd(II) and Pt(II) have been prepared and characterized; they have the general formulae of MX<SUB>2</SUB>L<SUB>2</SUB> and MX<SUB>2</SUB>L (X=Cl or Br). IR and <SUP>1</SUP>H NMR studies indicate that the latter complexes are <I>cis</I>-planar-chelate and involve both the pyrazolyl nitrogen and the olefinic group in bonding to the metal, while the former are <I>syn</I>- and <I>anti-trans</I>-planar and contain only uni-dentate pyrazole donor ligands. The treatment of the chelate complex PtCl<SUB>2</SUB>L(L=1-(2-methylallyl)-3,4,5-trimethylpyrazole) with donor ligands (L′) such as phosphines, AsPh<SUB>3</SUB>, and py displaces the coordinated olefin,forming <I>cis</I>-PtCl<SUB>2</SUB>LL′ with a retention of the <I>cis</I>-configuration.
