- Аннотация: The new copper(II) complexes [Cu(HL1 )(H2O)(CH3OH)] (1, H3L1 ¼ (Z)-2-(2-(1,3-dioxo-1-(phenylamino) butan-2-ylidene)hydrazinyl)benzoic acid) and [Cu(HL2 )(H2O)(CH3OH)] (2, NaH2L2 ¼ sodium (Z)-2-(2- (1,3-dioxo-1-(phenylamino)butan-2-ylidene)hydrazinyl)benzenesulfonate) were synthesized and characterized by IR and ESI-MS spectroscopies, elemental and X-ray crystal structural analyses. The coordination environment of the central copper(II) has a square pyramidal geometry, three sites being occupied by (HL1,2) 2, which chelates in the O,N,O fashion, while the two other sites are filled with the water and methanol ligands. Multiple intra- and intermolecular non-covalent interactions between the (HL1,2) 2, water and methanol ligands lead to supramolecular network. Both compounds 1 and 2 act as homogenous catalysts for the cyanosilylation reaction of a variety of both aromatic and aliphatic aldehydes with trimethylsilyl cyanide affording the corresponding cyanohydrin trimethylsilyl ethers in high yields (up to 90%) and at room temperature.
