内容記述
Siloxy-N-silylketenimines generated in situ from Osilyl cyanohydrins were converted to α-ketoamides by brief exposure to air or oxygen. Oxidation under extremely mild conditions can be explained by assuming the intermediacy of a 3-imino-1,2-dioxetane derivative generated via triplet−singlet intersystem crossing after the reaction of siloxy-N-silylketenimines with triplet oxygen.
