Cooperative photoredox- and nickel-catalyzed alkylative cyclization reactions of iodoalkynes with 4-alkyl-1,4-dihydropyridines as alkylation reagents under visible light irradiation have been achieved to afford the corresponding alkylated cyclopentylidenes in good to high yields. Introduction of substituents at the propargylic position of iodoalkynes has led to the stereoselective formation of E-isomers. The present reaction system provides a novel synthetic method for alkylative cyclization reactions of both terminal and internal alkynes with cooperative photoredox and nickel catalysis.

The partners decide: The C-C bond-forming reductive cross-coupling of alkenylboronic acids and tosylhydrazones takes place under mild reaction conditions without the need of a metal catalyst, thus giving rise to olefination-type products (see scheme). The position of the double bond in the product is determined by the structure of the coupling partners. Copyright
