ChemInform Abstract: VO(acac)₂: An Efficient Catalyst for the Oxidation of Aldehydes to the Corresponding Acids in the Presence of Aqueous H₂O₂.

Abstract

Aqueous H2O2. -The reaction provides a variety of carboxylic acids in an efficient manner in MeCN under either conditions A) or B), where similar yields are obtained. In methanol under conditions C), methyl esters are formed. Elevated temperatures render possible the preparation of ethyl esters. -(TALUKDAR, D.; SHARMA, K.; BHARADWAJ, S. K.; THAKUR*, A.

Synthesis of a Series of Methyl Benzoates through Esterification with a Zr/Ti Solid Acid Catalyst

“…The catalytic results are summarized in Table 3. The yields of the compounds (1,4,7,10,13) indicate that the presence of a large group in the ortho position decreased the yield. Orthosteric effects play a dominant role in the esterification process.…”

“…Methyl benzoate (MB) compounds are an important class of chemical products. Most of these compounds have low toxicity and are mainly used in scents and as solvents [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. For example, MB has a fruity flavor that can be used in pineapple, strawberry, and cherry syrups, and it as acts as a solvent in resin rubber.…”
