Vanadium-catalysed aerobic cleavage of C-C bonds in substituted cyclohexanones to afford carboxylic acids: Two model complexes with tetrahedral geometry around vanadium(V)
Two monosilanol/disilanol derivatives were synthesised by treatment of Ph3SiOH or Ph2Si(OH)2 with [nBu4N]VO3 (3) in ethanol solution. The mononuclear anionic dioxo vanadium(v) species [{Ph3SiO}2VO2]- (4) and the dinuclear complex anion [{Ph2SiO2VO2}2]2- (5) thus obtained are unusual and novel model compounds with ?Si-O-V(O)2O linkages characterised by single-crystal X-ray diffraction. The catalytic activities of these tert-butylammonium complexes, together with those of the simple vanadium derivatives 3 and 5, of the vanadyl precursors VOSO4¡¤5H2O (1) and [VO(acac)2] (2), and also of “H6[PMo9V3O40] ¡¤aq”, were tested for aerobic C-C bond cleavage in 2-hydroxycyclohexanone and 2-methylcyclohexanone. Monomeric vanadium species show the same chemistry as the polyoxometalate but with lower yields of acids or keto acids, and so the redox and acid properties of HPA-n (n = 3, 4) are better tuned. Mechanisms for these oxidation reaction, including electron transfer from a substrate coordinated to vanadium, are proposed. Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Related Products of 3153-26-2, you can also check out more blogs about3153-26-2
