In present work, the formation of α-hydroxycarboxylic acids have been described from various aromatic aldehydes and ketones via direct electrocarboxylation method with 80-92% of yield without any side product and can be purified by simple recrystallization using sacrificial Mg anode and Pt cathode in an undivided cell, CO2at (1 atm) was continuously bubbled in the cell throughout the reaction using tetrapropylammonium chloride as a supporting electrolyte in acetonitrile. The synthesized compounds obtained in fair to excellent yield with a high level of purity. The characterization of electrocarboxylated compounds was done with spectroscopic techniques like IR, NMR (1H & 13C), mass and elemental analysis.

Paragraph 0051; 0052, (2016/10/17)
The invention relates to the field of synthesis of carbonylfuran compounds and discloses a preparation method of the 2-carbonylfuran compounds adopting a structure shown in a formula (I). The method comprises the following steps: (1) a furan compound adopting a structure shown in a formula (II) and an aldehyde compound with the general formula of R1CHO have a condensation reaction in presence of an acid catalyst; (2) a condensation product in the step (1) and an oxidizing agent have an oxidation reaction under conditions of the oxidation reaction. Compared with the traditional method taking furan as the raw material and adopting acetylation and sodium nitrite oxidation technologies, the preparation method of the 2-carbonylfuran compounds has the advantages that few salts are contained in wastewater, the treatment is easy, the reaction technologies are clean and environment-friendly, and the yield is higher.
