CARBOXYLATION CATALYSTS
-
Paragraph 0086; 0087, (2013/04/13)
The use of a complex of the form Z—M—OR in the carboxylation of a substrate is described. The group Z is a two-electron donor ligand, M is a metal and OR is selected from the group consisting of OH, alkoxy and aryloxy. The substrate may be carboxylated at a C—H or N—H bond. The metal M may be copper, silver or gold. The two-electron donor ligand may be a phosphine, a carbene or a phosphite ligand. Also described are methods of manufacture of the complexes and methods for preparing isotopically labelled caboxylic acids and carboxylic acid derivatives.

Greenhouse gas makes good: A simple copper-mediated protocol has been developed where N-H or C-H bonds can be directly functionalized using an easily prepared catalyst. The novel [1,3-bis(2,6-diisopropylphenyl)imidazol-2-ylidene] copper(I) hydroxide, [Cu(IPr)(OH)], permits the facile activation and carboxylation of N-H and C-H bonds with pKavalues of less than 27.7 (see scheme).

, (2008/06/13)
The present application describes oxygen and sulfur containing heteroaromatics and derivatives thereof of formula or pharmaceutically acceptable salt or prodrug forms thereof, wherein J is O or S and D may be C(=NH)NH2, which are useful as inhibitors of factor Xa.
