Grafting of oxo-vanadium Schiff base on graphene nanosheets and its catalytic activity for the oxidation of alcohols

Coordination chemistry on carbon surfaces

“…Salicaldehyde was also reacted with amino-functionalized carbon materials to form a supported Schiff base ligand for oxovanadium [377] or copper [363] onto GO and for molybdenum [378] onto MWCNT (Table 17, entries 5-7). Similarly, Kan et al covalently attached a salen-type ligand onto GO by nucleophilic substitution between the chloro-modified salen and the aminofunctionalized support (Table 17, entry 8) [379][380][381].…”

Oxidovanadium complexes with tridentate aroylhydrazone as catalyst precursors for solvent-free microwave-assisted oxidation of alcohols

“…The use of polyoxidovanadates has also been reported for the efficient oxidation of benzylic alcohols to the corresponding carbonyl compounds with p-toluenesulfonic acid [40]. However, the vanadium catalyzed peroxidative oxidation of secondary alcohols is comparatively scarce [35][36][37][38][39][41][42][43]. Some efficient systems concern the use of tert-butylhydroperoxide (TBHP) in the presence of silica [41] or graphene [42] supported oxidovanadium Schiff bases, or of hydrogen peroxide in a homogeneous mixture composed of vanadate, acid and TEMPO functionalized ionic liquids [43].…”

Selective Oxidation of Alcohols Using Photoactive VO@g-C3N4

“…8 Heterogenized catalyst have been developed to circumvent the problem of waste generation. [9][10][11] Most of the reported catalysts employed for such reactions involve precious metals such as palladium, gold, silver etc. [12][13][14] Recently, scientists have focused on the use of organic material such graphene oxide, 15 N-doped graphene, 16 thiourea dioxide, 17 graphitic carbon nitride [18][19][20][21][22][23] in oxidation chemistry.…”
