Abstract
A graphitic carbon nitride/lead-free double perovskite heterojunction (g-C3N4/Cs2AgBiCl6) has been adopted as a heterogeneous photocatalyst under visible light irradiation. The employed material enabled the atom transfer radical addition-type carbohalogenation of multiple C–C bonds, including (internal) alkenes and alkynes, with alkyl halides. The protocol showed a remarkable functional group tolerance, compatible with the late-stage functionalization of natural and pharmaceutical derivatives, and could be easily scaled up, delivering >1 g of the desired products.
期刊介绍：
Organic Letters invites original reports of fundamental research in all branches of the theory and practice of organic, physical organic, organometallic,medicinal, and bioorganic chemistry. Organic Letters provides rapid disclosure of the key elements of significant studies that are of interest to a large portion of the organic community. In selecting manuscripts for publication, the Editors place emphasis on the originality, quality and wide interest of the work. Authors should provide enough background information to place the new disclosure in context and to justify the rapid publication format. Back-to-back Letters will be considered. Full details should be reserved for an Article, which should appear in due course.
