A novel, metal-free oxidation system for the catalytic synthesis of aldehydes and ketones using TEMPO and a quarternary ammonium salt as catalysts and Oxone as oxidant proved especially successful for the synthesis of ketones. The mild conditions tolerate even sensitive silyl protective groups which can otherwise be cleaved in the presence of Oxone.
