Dichloropalladium(II)‐Komplexe mit α‐Aminosäuren, α‐Aminosäureestern, Dipeptiden und Dipeptidestern

Abstract

Eine Reihe von (runs-Dichloropalladium(I1)-Komplexen CI,PdL, mit (L = a-Aminosaure, a-Aminosaureester, Dipeptid, Dipeptidester) sowie cis-CI,Pd(Histidin) wurde dargestellt und spektroskopisch charakterisiert. Die Rontgenstruktur von trans-CI,Pd(GlyOEt), (3 b) wurde bestimmt . Dichloropalladium(l1) Complexes with a-Amino Acids, a-Amino Acid Esters, Dipeptides, and Dipeptide EstersA series of frans-dichloropalladium(I1) complexes CI,PdL, (L = a-amino acid, a-amino acid ester, dipeptide, dipeptide esters) and cis-CI,Pd(histidine) has been prepared and spectroscopically characterized. The X-ray structure of trans-Cl2Pd(GlyOEt), (3b) has been determined.

Metal Complexes of Biologically Important Ligands, CLXXVII. Dichlorido Platinum(II) and Palladium(II) Complexes with Long Chain Amino Acids and Amino Acid Amides

“…The palladium complex Cl 2 Pd(histOH) was prepared, as first described by us, from Na 2 PdCl 4 and histidine. This histidine palladium complex was often studied: its structure was determined by X‐ray diffraction, and theoretical studies on the vibrational spectra were reported . Using the free carboxylic group of Cl 2 Pd(histidine) steroids could be attached .…”

“…The starting complexes Cl 2 Pd(histidine) and Cl 2 Pt(NH 2 CH 2 COCl) 2 were prepared as described. Usually the solid complexes were separated from solutions by centrifugation, using a Macrofuge 6–4, Heräus‐Christ.…”

Glycine ethyl ester hydrochloride

“…The title compound is an intermediate in the synthesis of dichlorovinylcyclopropane carboxylic acid, see: Xue (1995). For related structures, see: Taubald et al (1984); Gainsford et al (1986); Eduok et al (1994).…”

“…(2010). E66, o2115 The title compound, glycine ethyl ester hydrochloride is used in the preparation of dichlorovinylcyclopropane carboxylic acid, an important pesticide intermediate (Xue,1995).It is also used in the preparation of function material, the crystal structures of dichloro-bis(glycine ethyl ester)-palladium(II) (Taubald, et al, 1984),p,p-(µ 2 -peroxo) -bis(tris(2-aminoethyl)-amine-N,N′,N′′,N′′′)-bis(ethylglycinate-N)-cobalt(II) tetraperchlorate (Gainsford et al, 1986),cis-β 2 -((s,s)chloro-(glycine ethyl ester-N)-(triethylenetetramine)-cobalt(III) dichloride trihydrate (Eduok et al, 1994) have been reported. The molecular structure of(I) is shown in Fig.1.…”

Pt(II) and Pd(II) Complexes with β‐Alanine

“…The study of the Pt(II) and Pd(II) complexes with amino acids is very promising due to both of their biological activity and their use in the solution of the fundamental problems in coordination chemistry of planar complexes with multifunctional ligands. The Pt(II) and Pd(II) complexes with α -alanine (NH 2 CH(CH 3 )COOH) are widely described in the literature [2–8]. …”
