C2-alkylation of benzothiazoles with aliphatic carboxylic acids was disclosed. In the presence of an acridinium salt as a photocatalyst and air as an oxidant, a wide range of secondary or tertiary aliphatic carboxylic acids were employed as alkylation reagents, providing the desired products in good to excellent yields under mild reaction conditions with a broad substrate scope.
A metal-free deformylative Minisci-type reaction is disclosed by using aliphatic aldehydes as alkyl radical precursors. The reaction proceeds via a sequence of hydrogen atom abstraction (HAA) from aldehyde and decarbonylation under mild photochemical conditions. The transformation offers many advantages including good regioselectivity, broad substrate scope, and easy operation. The reaction is also
