The use of alkyl diacyl peroxides and alkyl tert-butyl peresters, which are readily accessible from carboxylic acids, enables an efficient, iron-catalyzed C-H alkylation of benzothiazoles. This reaction is environmentally benign and compatible with a broad range of functional groups. Various primary, secondary, and tertiary alkyl groups can be efficiently incorporated.
