Reactions of Pd/NHC complexes with various amines within a temperature range of 25–140 °C and thermalstability of the resulting amino-complexes are examined. The results indicate the major influence of the amine structure and reaction temperature on the catalyst transformation. In particular, thermal decomposition of Pd/NHC complexes with aliphatic amine ligands predominantly leads to reductive Pd–NHC
