چکیده

The nature of the anionic ligand X (X = EtOSO3, BF4, Cl, Br, OSO2CF3, F or CN) in vanadium(V)salen complexes [V+ O(salen) X-] was found to have a significant influence on the catalytic activity of the complexes, but not on their enantioselectivities; with the complexes in which X = Cl or F being most active and the complex with X = OSO2CF3 being totally inactive.

Kinetics and mechanism of vanadium catalysed asymmetric cyanohydrin synthesis in propylene carbonate

Propylene carbonate can be used as a green solvent for the asymmetric synthesis of cyanohydrin trimethylsilyl ethers from aldehydes and trimethylsilyl cyanide catalysed by VO(salen)NCS, though reactions are slower in this solvent than the corresponding reactions carried out in dichloromethane. A mechanistic study has been undertaken, comparing the catalytic activity of VO(salen)NCS in propylene...

Cyanogen formation during asymmetric cyanohydrin synthesis.

During asymmetric cyanohydrin synthesis catalysed by vanadium(V)oxo(salen) complexes, the catalysts are reduced to vanadium(IV)oxo(salen) as determined by EPR spectroscopy; the reducing agent is cyanide which is oxidised to cyanogen via a non-radical mechanism.

Synthesis and Crystal Structure of Cobalt(III) Complexes of Salen Type Schiff Bases and Tertiary Phosphanes as Ligands

The new [Co(Salen)(PBu3)2]ClO4, [Co(Salen)(PBu3)2]BF4, [Co(Salpn)(PBu3)2]ClO4 and [Co(Salen)(PMe2Ph)2]ClO4 ( where salen = bis(salisylaldehyde)ethylenediimine)) complexes were synthesiszed and chracterized by IR, UV-Vis, 1H NMR spectroscopy and elemental analysis. The IR and 1H NMR spectra cofirmed that the synthesised complexes contain Schiff base ligand, phosphane and conter ion and the eleme...
