We herein described a selenylative cyclization reaction of enynes by the utilization of diselenides as radical sources. The visible-light irradiation of the reaction mixture enables the generation of the selenium atomradical to trigger the radicaladdition/cyclization/selenation sequences. Both terminal alkyne and internal alkyne derived 1,6-enynes were tested and suitable for the current synthetic
Graphitic Carbon Nitride as a Heterogeneous Photocatalyst for the Hydrophosphorylation and Hydrophosphorylative Cyclization Reactions of Terminal Alkyne and Its Derived Enynes
Heterogeneous graphitic carbon nitride as the photocatalyst for radical hydrophosphorylation and hydrophosphorylative cyclizationreactions were accomplished, providing a new opportunity to access phosphorylated alkene and cyclic products under redox-neutral conditions.
