| Abstract: | The reaction of Ru3(CO)12 with 2-methyl-3-morpholino-1-phenylprop-2-en-1-one (1) produced the Ru6(CO)16(μ4-η1:η1:η2:η2-PhC(O)-C(Me)=C)2 (2), Ru2O2(CO)4(η3-OC(Ph)C(Me)C(H)C(Me)2C(Ph))2 (3), and [Ru(CO)2(PhCO2)(O(CH2-CH2)2NH]2 (4) complexes, which were characterized by IR and NMR spectroscopy. The structures of the complexes were established by X-ray diffraction. The formation of the complexes is accompanied by deamination of ligand 1. Complexes 2 and 3 bearing the vinyl ketone groups contain five-membered oxaruthenacycles and dihydropyran rings. Morpholine is not removed from the reaction mixture and leads to the formation of complex 4. Published in Russian in Izvestiya Akademii Nauk.
