	Title	Metallkomplexe mit biologisch wichtigen Liganden, CIV [1]. or/Zio-Palladierte Komplexe von N,N-DimethyI-C-phenyl-glycinmethylester. Synthese von a-Aminosäure-Derivaten durch Insertion von Isocyaniden, CO, Alkenen und Alkinen in die Pd-C-Bindung Metal Complexes of Biologically Important Ligands, CIV [ 1]. o/t/20-Palladated Complexes of N,N-Dimethyl-C-phenylglycine-methylester. Synthesis of ct-Amino Acid Derivatives by Insertion of Isocyanides, CO, Alkenes, and Alkynes into the Pd-C Bond
	Abstract	-phenylglycinemethylester reacts with Pd(OAc)2 in acetic acid to give the orthopalladated, acetato bridged complex 1. Treatment of 1 with sodium halide affords the chlo-ro, bromo, and iodo bridged compounds [Me2N C (H)(C 02Me)C6H4PdX]2 (2a -c) (X = halide). From 2a and 1,1 '-bis(diphenylphosphino)ferrocene the phosphine bridged trinuclear complex 3 is obtained. Substitution of the amine ligand of 2a by the phosphino group is observed for the reaction of 2a with Ph2PC(Me)C(Me)PPh2. Insertion of 2,6-dimethyl-phenylisocyanide, CO, alkyl-vinyl-ketones, and diphenylacetylene into the Pd-C bond o f 2a -c provides the ortho substituted organic and organometallic derivatives of phenylglycine 6a -c, 7, 8a -b and 9a -c. The crystal structures of 1, 4a, 6a, 7 and 9a were determined by X-ray diffraction.
