H2O2-HBr: A metal-free and organic solvent-free reagent system for the synthesis of arylaldehydes from methylarenes

A novel, practical and environmentally benign approach has been developed for the oxidation of methylarenes using H 2 O 2 -HBr system in water. Arylaldehydes containing electon-withdrawing groups are isolated in good to high yields. Methylarenes containing electon-donating groups, in contrast, are t...

Zusammenfassung:	A novel, practical and environmentally benign approach has been developed for the oxidation of methylarenes using H 2 O 2 -HBr system in water. Arylaldehydes containing electon-withdrawing groups are isolated in good to high yields. Methylarenes containing electon-donating groups, in contrast, are transformed into bromo-substituted arylaldehyde undergoing a tandem oxidation-bromination process.
