Abstract:
The invention provides a new process for producing ruthenium complexes represented by the Formula 1. Invention provides also the use of ruthenium complexes represented by the Formula 1 as precatalysts and/or catalysts in olefin metathesis reactions.

Claim (Index 3):
A process for producing compound represented by the Formula 1 according to  claim 1 , characterised in that carbenes represented by the Formula 3 are provided to the reaction medium by their generation in situ from suitable carbene precursors, CAAC salts represented by the Formula 3a, wherein: Ar is an aryl group substituted with hydrogen atoms or optionally substituted with at least one C 1 -C 12  alkyl, C 1 -C 12  perfluoroalkyl, C 1 -C 12  alkoxy, C 5 -C 24  aryloxy, and C 5 -C 20  heteroaryloxy group, or a halogen atom; R 7 , R 8 , R 9 , and R 10  are each independently hydrogen atom, or C 1 -C 25  alkyl group, R 7  and/or R 8  can be combined with R 9  and/or R 10  to form cyclic system, can be also independently C 1 -C 12  alkyl, C 3 -C 12  cycloalkyl, C 2 -C 12  alkenyl, C 5 -C 20  aryl, C 1 -C 5  perfluoroalkyl, C 7 -C 24  aralkyl, and C 5 -C 24  perfluoroaryl group, which are optionally substituted with at least one C 1 -C 12  alkyl, C 1 -C 12  perfluoroalkyl, C 1 -C 12  alkoxy, C 5 -C 24  aryloxy, C 5 -C 20  heteroaryloxy, or a halogen atom; X \u2212  is a halide anion, or BF 4 \u2212 , PF 6 \u2212 , ClO 4 \u2212 , CF 3 SO 2 O \u2212 ; involving contacting compound represented by the Formula 3a with suitable base selected from potassium N,N\u2032-bis(trimethylsilyl)amide, lithium N,N\u2032-bis(trimethylsilyl)amide, sodium N,N\u2032-bis(trimethylsilyl)amide, potassium tert-amylate, potassium tert-butoxide, sodium hydride.
