    Abstract: The invention relates to a bismuth-containing catalyst as such, which is defined by the general formula (I) detailed in the subsequent text. The bismuth-containing catalyst comprises at least one residue R1, which comprises a carboxyl fragment according to the general formula (II), wherein the first carbon atom (α-carbon), which is bonded directly to the carbon atom of the carboxyl group, is part of an aromatic fragment. The present invention further relates to a method for preparing a bismuth-containing catalyst of this kind and also to the use of such a bismuth-containing catalyst for preparing compounds comprising a urethane group.

    Abstract: Die Erfindung betrifft einen zinkhaltigen Katalysator als solchen, der über die im nachfolgenden Text aufgeführte allgemeine Formel (I) definiert ist. Der zinkhaltige Katalysator enthält mindestens einen Rest R1, der gemäß der allgemeinen Formel (II) ein Carboxyl-Fragment enthält, wobei an das Kohlenstoffatom der Carboxyl-Gruppe ein erstes Kohlenstoffatom (α-Kohlenstoff) gebunden ist, das wiederum erfindungsgemäß mit mindestens einem Aromaten direkt substituiert ist. Die vorliegende Erfindung betrifft weiterhin ein Verfahren zur Herstellung eines solchen zinkhaltigen Katalysators sowie die Verwendung eines solchen zinkhaltigen Katalysators zur Herstellung von Verbindungen, die eine Urethan-Gruppe enthalten.

    Abstract: The present invention relates to a mixture comprising the components (A) and (B) and optionally the further component (C). Component (A) comprises at least one bismuth- containing catalyst which is defined by the general formula (I) detailed in the subsequent text. The bismuth-containing catalyst comprises at least one radical R1, which comprises a carboxyl fragment according to the general formula (II), wherein a 10 first carbon atom (α-carbon) is bonded to the carbon atom of the carboxyl group, which in turn is directly substituted with at least one aromatic system. Component (B) of the inventive mixture is at least one hydrocarbon compound containing two hydroxyl groups ("diol"). The optionally present component (C) is at least one solvent.
