Аннотация: Thermal reaction of Ru3(CO)12 with 1-(4-tolyl)-3-phenylaminoprop-2-en-1-one (1) proceeds in heptane with the formation of a number of new chelate mononuclear complexes cis-Ru(CO)2[O=C(Tol)CH=CHNPh]2 (2), cis-Ru(CO)2[O=C(Tol)CH=CNHPh][O=C(Tol)CH=CH-NPh] (3), cis-Ru(CO)2[O=C(Tol)CH=CNHPh][O=C(Tol)CH=CHNPh] (4), isolated as the main products, along with minor amounts of the polynuclear clusters Ru5(CO)14(2-H)2(4-η1:η1:η2:η2-CCHC(Tol)=O) (5), Ru4(CO)11(2-H)2(4-η2:η2:η1:η2-NPhCCHC(Tol)=O) (6) and Ru4(CO)12(4-η1:η1:η1:η1-NPhCHCC(Tol)=O) (7). Complexes of both series were characterized by a combination of spectroscopic IR and multinuclear NMR data and by single-crystal X-ray diffraction study which revealed the existence of different types of metal-to-ligand bonding in these species. Chelate six-membered azaoxaruthenacycles are formed in 2-4 via N-H activation, while unexpected five-membered oxaruthenacycles are formed in 3-6 due to Cβ-H activation reaction. Among the products of the reaction the butterfly cluster 7 with open-chain coordination of the ligand formed as a result of the N-H and Cα-H bonds activation is also isolated. Complex 5 proved to be the only reaction product in which the deamination of aminovinylketone 1 is observed. Possible pathways for the formation of the complexes obtained are discussed in the paper.
