Photocatalyzed <italic>ortho</italic>‐Alkylation of Pyridine <italic>N</italic>‐Oxides through Alkene Cleavage.

Abstract: A photocatalyzed reaction of pyridine <italic>N</italic>‐oxides with alkenes gives <italic>ortho</italic>‐alkylated pyridines with cleavage of the carbon–carbon double bond. Benzyl and secondary alkyl groups are incorporated at the <italic>ortho</italic> position of pyridines in one pot. [ABSTRACT FROM AUTHOR]
