Photocatalyst-free visible-light-mediated three-component reaction of α-diazoesters, cyclic ethers and NaSCN to access organic thiocyanates

A facile and environmentally friendly visible-light-induced three-component reaction of α -diazoesters, cyclic ethers and NaSCN to construct organic thiocyanates has been developed at room temperature. This reaction could occur under photocatalyst- and additive-free conditions to afford a number of organic thiocyanates with moderate to good yield and favorable functional group tolerance. GRAA facile and green visible-light-induced protocol for the assembly of organic thiocyanates from α -diazoesters, cyclic ethers and NaSCN has been described. This three-component reaction could undergo smoothly under mild conditions to afford a series of structurally diverse organic thiocyanates in moderate to good yields.
