Abstract

Abstract A central aspect of the present work was to find the synthesis and characterization of new homoleptic Wolfram(VI)-komplexes with ligands engaged organic about oxygen. These complexes should lead built-in in heart catheter as X-ray active additional materials to the fact that one can pursue the catheter by X-ray device after introduction to the human fabric immediately. To increase the contrast effect from medicinal catheter tubes under the X-ray screen, are added to the base polymer either a contrast medium usual in medicinal technices (e. g. metallic wolfram powder), or one or several contrast stripes are trained directly in the tube wall with. This training of usual contrast media leads to substantially higher surface roughness which also thrombogene effects owns. With the made connections should be tried to demonstrate the catheter even able of X-ray examination to be able to assess with it an additional sputter of X-ray contrast medium in the vessels, only in order the situation of the catheter can be prevented. With it a part of the contrast medium-conditioned side effects should be eliminated. The following connections were synthesized: Tris(1,3-propandiolato)wolfram(VI); Tris(2,2-dimethyl-1,3-propandiolato)-wolfram(VI); Tris(2,4-pentandiolato)wolfram(VI); Tris(2-tert.-butyl-1,3-propandiolato)wolfram(VI); Tris(2,2,4-trimethyl-1,3-pentandiolato)-wolfram(VI) und Tris(2-Methyl-2-propyl-1,3-propandiolato)wolfram(VI). However, the application in polymers for the use in catheter tubes was not made in this work.
