Abstract

A catalyst‐free carbopyridylation reaction of maleimides with N‐benzoylmethylpyridinium bromides under visible light irradiation is reported. The carbo‐2‐pyridylation products of maleimides are obtained in good yields, demonstrating broad substrate scope and high functional group tolerance even on a gram scale. Mechanistic studies suggest that the process involves a tandem [3+2] cycloaddition, and Norrish‐type‐II fragmentation.

期刊介绍： Organic chemistry is the fundamental science that stands at the heart of chemistry, biology, and materials science. Research in these areas is vigorous and truly international, with three major regions making almost equal contributions: America, Europe and Asia. Asia now has its own top international organic chemistry journal—the Asian Journal of Organic Chemistry (AsianJOC) The AsianJOC is designed to be a top-ranked international research journal and publishes primary research as well as critical secondary information from authors across the world. The journal covers organic chemistry in its entirety. Authors and readers come from academia, the chemical industry, and government laboratories.
