Filed:

Jan 19, 2002

Appl. No.:

10/470260

Inventors:

Hans-Ulrich Wustefeld - Bottrop, DE
William Kaska - Goleta CA, US
Galen Stucky - Goleta CA, US
Ferdi Schuth - Mullheim an der Ruhr, DE

Assignee:

Studiengesellschaft Kohle MbH - Mulheim an der Ruhr

International Classification:

C07F 15/00

US Classification:

556136000, 546002000

Abstract:

Transition metal complexes with quino[7,8-h]quinolines and cyclopentadieno[1,2-h:4,3-h′]diquinolines as proton sponge ligands and a process for their preparation. These complexes are suitable as catalysts, e.g. the palladium complexes for a Heck reaction, as well as for amination and C—H activation reactions. The platinum and palladium complexes are potentially good cytostatic agents.

C07C 5333
C07F 1502

US Classification:

585654

Abstract:

An improved process is described for the catalytic dehydrogenation of organic molecules having a ##STR1## group to produce a ##STR2## group. The organic molecules are: ##STR3## wherein: A. sup. 1, A. sup. 2, A. sup. 3, and A. sup. 4 are each independently P, As or N: E. sup. 2 is independently C or N; E. sup. 3 is independently C, Si or Ge; E. sup. 4 is independently C, Si, or Ge; and E. sup. 5 is independently C, Si or Ge; M. sup. 1, M. sup. 2, M. sup. 3, and M. sup. 4 each is a metal atom independently selected from the group consisting of ruthenium, rhodium, palladium, osmium, iridium and platinum; Q. sup. 1, Q. sup. 2, Q. sup. 3, and Q. sup. 4 are each independently a direct bond, --CH. sub. 2 --, --CH. sub. 2 CH. sub. 2 --, or CH. dbd.
