-
Page/Page column 11-13, (2019/02/25)
Disclosed is a new process for the production of carboxylated phenol derivatives comprising at least a step of carboxylation of a mixture of (i) phenol derivative and (ii) phenolate derivative, wherein the molar ratio of (i) / (ii) is comprised between 0.8 and 1.2, in presence of CO2. A process for the production of said mixture of (i) phenol derivative and (ii) phenolate derivative is also disclosed.

We report the oxidation of a wide range of alcohols using an environmentally benign and economical process. The use of Pd/C heterogeneous catalysts along with NaBH4in aqueous ethanol or methanol and either K2CO3 or KOH as base at room temperature under molecular oxygen or air give the corresponding oxidation products. This protocol is versatile since it is capable of oxidizing alcohols to its desired carbonyl or carboxyl counterpart. Room temperature reaction in aqueous system and recyclability of the catalyst are among the advantages of this manipulation. These advantages make the process safe and cheaper rendering it favorable from both economic and environmental viewpoints. Georg Thieme Verlag Stuttgart New York.

Pd/C catalyst in aqueous methanol with sodium borohydride and potassium hydroxide under the air efficiently oxidized aldehydes to their corresponding carboxylic acids at room temperature. The utilization of room temperature reaction, aqueous methanol solvent, and the open-air conditions make this manipulation very interesting for economic and environmental perspectives.
