The reduction of organic compounds is one of the important synthetic processes both in the laboratory and industrially. Transfer hydrogenation, which is practically carried out with metal catalysis, is an important reaction in this respect. Since hydrogen donor molecules are used instead of gaseous hydrogen in the reduction of multiple bonds, it is economical, mild and environmentally friendly. [1] Hydrogen donors such as molecular hydrogen, alcohol, formic acid are catalytically activated by suitable metals or metal complexes. It is known that many Ru, Rh and Ir compounds reduce different substrates in both homogeneous and heterogeneous phases. [2,3] In this study, 5,6-dimethylbenzimidazol-2-ylidene salts, which were synthesized and whose structures were elucidated by spectroscopic methods, were converted into ruthenium-carbene complexes in the reaction medium and their catalytic activation in the transfer hydrogenation reaction of acetophenone derivatives was investigated. When the results were examined, it was seen that this catalyst system was active.
