A convenient and eco-friendly visible-light promoted multicomponent protocol has been developed for the synthesis of S-alkyl phosphorothioates by using elemental sulfur as the cheap and odorless sulfur source.

A simple visible-light-initiated strategy has been established for the construction of organophosphorus compounds via aerobic multicomponent reaction of α-diazoesters, cyclic ethers, and P­(O)H compounds under air. A number of phosphonates and phosphinates could be efficiently isolated in moderate to good yields without the use of photosensitizers and metal reagents. This multicomponent reaction has advantages of mild condition, simple operation, eco-friendly energy, good functional-group tolerance, and gram-scale synthesis.

A visible-light-promoted strategy has been developed for the assembly of multisubstituted pyrazoles and 1,3-dicarbonyl derivatives via a multi-component carbene transfer reaction of α-diazoesters.

An eco-friendly and photocatalyst-free visible-light-promoted four-component reaction of α-diazoesters, elemental sulfur, cyclic ethers and TMSCN leading to thiocyanates is described.

A simple and green visible-light-initiated strategy for the installation of cyano and azido groups has been established through multi-component reaction of α-diazoesters, cyclic ethers and TMSCN/TMSN 3 . A number of structurally diverse organic nitriles and azides could be efficiently obtained at room temperature without adding any external metal reagent, strong oxidant, base and photocatalyst. The synthetic transformations of the reaction products to some functionalized molecules were carried out to highlight the potential utility of this method.
