Abstract |
The self-assembly reaction of the Schiffbase N,N -ethylenebis(2-hydroxyacetophenoneimine) (H2L), CoCl2 center dot center dot center dot 6H(2)O and [SnPh2Cl2] led to the alkoxo-bridged heteroorganometallic (CoSnIV)-Sn-III complex [\SnPhCl2\(1 kappa O-2:2 kappa O-2 N-2-mu-L)(mu-OMe)\CoPh\]center dot CH3OH center dot H2O (1) or [\SnPhCl2\(1 kappa O-2:2 kappa O-2 N-2-mu-L)(mu-OEt)\CoPh\] (2) in MeOH or EtOH, respectively. The structures of these complexes are authenticated by single crystal X-ray diffraction analyses. They are derived from an intermetallic (Sn to Co) phenyl shift, leading to face-shared distorted octahedral coordination geometries. The complexes were tested as homogeneous catalysts for the solvent-free cyanosilylation reaction of benzaldehyde with trimethylsilyl cyanide (TMSCN) under low power microwave irradiation at 50 degrees C. They exhibited a high catalytic activity, yielding (for catalyst 1) up to 93\% of the cyano-derivative from benzaldehyde in 90 minutes. (C) 2021 Elsevier B.V. All rights reserved. |
