Oxidative decarboxylation of arylacetic acids and arylacetic esters with singlet molecular oxygen generated from trans-5-hydroperoxy-3,5-dimethyl-1,2-dioxolan-3-yl ethaneperoxate
An efficient method for the oxidative decarboxylation of arylacetic acids and arylacetic esters using trans-5-hydroperoxy-3,5-dimethyl-1,2-dioxolane-3-yl ethaneperoxate in combination with KOH as base is reported. The decarboxylation of carboxylic acids and their derivatives was efficiently achieved with singlet molecular oxygen. Singlet molecular oxygen was produced in situ from the fragmentation of the trans-5-hydroperoxy-3,5-dimethyl-1,2-dioxolane-3-yl ethaneperoxate in the presence of KOH, and it has been explored as an effective oxidant for oxidative decarboxylation of arylacetic acids. Further investigation showed that the reaction also permits the synthesis of aromatic ketones by oxidative decarboxylation of arylacetic esters.
Graphical abstract
An efficient method for the oxidative decarboxylation of arylacetic acids and arylacetic esters is reported.The decarboxylation of carboxylic acids and their derivatives were efficiently achieved with singlet molecular oxygen. Singlet molecular oxygen was produced insitu from fragmentation of the trans-5-hydroperoxy-3,5-dimethyl-1,2- dioxolane-3-yl ethaneperoxate in the presence of KOH, and it has been explored as an effective oxidant for oxidative decarboxylation of arylacetic acids and arylacetic esters.
期刊介绍：
Journal of Chemical Sciences is a monthly journal published by the Indian Academy of Sciences. It formed part of the original Proceedings of the Indian Academy of Sciences – Part A, started by the Nobel Laureate Prof C V Raman in 1934, that was split in 1978 into three separate journals. It was renamed as Journal of Chemical Sciences in 2004. The journal publishes original research articles and rapid communications, covering all areas of chemical sciences. A significant feature of the journal is its special issues, brought out from time to time, devoted to conference symposia/proceedings in frontier areas of the subject, held not only in India but also in other countries.
