Hydroxy Esters

Selective oxidation of α-hydroxy esters is one of the most important methods to prepare high value-added α-keto esters. An efficient catalytic system consisting of Zn(NO3)2/VOC2O4 is reported for catalytic oxidation of α-hydroxy esters with molecular oxygen. Up to 99% conversion of methyl DL-mandelate or methyl lactate could be facilely obtained with high selectivity for its corresponding α-keto ester under mild reaction conditions. Zn(NO3)2 exhibited higher catalytic activity in combination with VOC2O4 compared with Fe(NO3)3 and different nitric oxidative gases were detected by situ attenuated total reflection infrared (ATR-IR) spectroscopy. UV-vis and ATR-IR results indicated that coordination complex formed in Zn(NO3)2 in CH3CN solution was quite different from Fe(NO3)3; it is proposed that the charge-transfer from Zn2+ to coordinated nitrate groups might account for the generation of different nitric oxidative gases. The XPS result indicate that nitric oxidative gas derived from the interaction of Zn(NO3)2 with VOC2O4 could be in favor of oxidizing VOC2O4 to generate active vanadium (V) species. It might account for different catalytic activity of Zn(NO3)2 or Fe(NO3)3 combined with VOC2O4. This work contributes to further development of efficient aerobic oxidation under mild reaction conditions.

In this work, a promising method for production of high value-added aromatic aldehydes from lignin was proposed. The concept is based on the use of metalloporphyin as catalyst and hydrogen peroxide as oxidant under alkaline condition. The biomimetic catalyst Co (TPPS4) (TPPS4=meso-tetra (p-sulphonatophenyl) porphyrin) was prepared and characterized by1H-NMR spectroscopy, FT-IR spectroscopy and UVvisible spectroscopy. It exhibited high activity in the catalytic oxidation of lignin. The main products were p-hydroxybenzaldehyde, vanillin, and syringaldehyde from catalytic oxidation of lignin, which in total were up to 75.09% of the identified compounds by GC-MS. The yield of the three aromatic aldehydes was 12.84 wt.%, compared to a poor 2.63 wt.% yield of the three aromatic aldehydes without Co (TPPS4).
