Organic acids as efficient catalysts for microwave-assisted synthesis of xanthenones

Terra, Bruna Silva; Fátima, Ângelo de

Abstract:

Organocatalysis is a process in which metal-free organic molecules are used to accelerate the rate of chemical reactions. The use of organocatalysts has also been increased due to their low toxicity to the environmental and low sensitivity to oxygen. Natural organic acids (NOA) are biodegradable and thus considered eco- and user-friendly alternatives to synthetic organocatalysts. This work aimed to evaluate oxalic, malonic, succinic and acetic acids as potential organocatalysts for microwave-assisted synthesis of xanthenones under solvent-free conditions.
