An efficient, iron-catalyzed C-H alkylation of benzothiazoles by using alkyl diacyl peroxides and alkyl tertbutyl peresters which are readily accessible from carboxylic acids to synthesize 2-alkylbenzothiazoles is developed. 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 into diverse benzothiazoles. The effectiveness of this method is illustrated by late-stage functionalization of biologically active heterocycles.

Synthetic methods: The Ni-catalyzed alkylation of 2-(methylthio) benzothiazoles through C-S bond cleavage is reported. Reactions with various secondary alkyl nucleophiles proceeded efficiently in the presence of 1,3-butadiene as an additive. This reaction was proposed to proceed by σ-bond metathesis between the thioether and a bis(π-allyl)nickel complex or by an addition/elimination mechanism involving the C=34;N double bond of the benzothiazoles (see scheme).
