A novel oxyfluorination of olefin reactions has been developed. The reactions involve a metal-free and green catalytic system for the synthesis of α-fluoroketones which is an important building block for organic synthesis. Moreover, this reaction system exhibits great functional group tolerance.

A novel metal-free oxidative carbonitration of alkenes by a nitration and C-H functionalization cascade process has been developed. This methodology provides an efficient way to construct valuable nitro-containing oxindoles.

The low‐cost cobalt(II) catalyst has been used for the first time to achieve P(O)‐radical‐mediated bisfunctionalization of alkenes with diarylphosphine oxide and peroxides. This simple process is performed under mild conditions to afford a wide variety of phosphonation‐peroxidation products in a one‐pot manner. Computational studies are carried out to provide a theoretical support for the P(O)‐radical‐involved bisfunctionalization of alkenes. [ABSTRACT FROM AUTHOR]

A Cerium(IV)‐promoted phosphinoylation‐nitratation of alkenes is established under mild conditions. In this process, Ceric ammonium nitrate (CAN) acts as a cheap phosphorus‐radical initiator, as well as a nitrate donor. Various β‐nitrooxyphosphonates are delivered in high yield in a one‐pot manner.

Abstract: An efficient and practical method for the synthesis of α,α‐difluoro‐γ‐aminophosphonates through photocatalyzed intermolecular aminodifluoromethylphosphonation of alkenes has been developed. In this reaction, difluoromethylphosphonate is used as an important fluorinated reagent. Furthermore, the mild reaction conditions, simple operation, and broad substrate scope make this protocol very practical and attractive. The derivatization reaction in the synthesis of difluoromethylphosphonated chiral binaphthylamine ligands and α,α‐difluoro‐γ‐aminophosphoric acid highlight the applicability of this method.

Abstract: A novel arylnitration of alkenes by nitration and C–H functionalization cascade process has been developed. This methodology provides an efficient way to construct a variety of nitro-containing oxindoles and dihydroquinolin-2(1H)-ones. In addition, the process exhibits significant functional group tolerance. Moreover, the use of inexpensive and readily available starting materials makes this practical and atom-economical approach particularly attractive. [Copyright &y& Elsevier]

The Pd(II)-catalyzed Ph2(O)P-directed C–H olefination to synthesize alkene–phosphine compounds is reported. In contrast to previous examples of various directing groups that guide selective C–H activation, the Ph2(O)P group not only acts as the directing group but also serves to construct the alkene–phosphine ligands. The monoprotected amino acid (MPAA) ligand Ac-Leu-OH is found to promote this reaction in a significant manner. [ABSTRACT FROM AUTHOR]

Abstract: A new method for the synthesis of tricyclic 2,3-dihydro-4-quinolones by the NiCl2(PMe3)2-catalyzed carboamination of alkenes by intermolecular decarboxylative cycloaddition reaction is reported here. Isatoic anhydrides were reacted with various norbornenes to afford the novel structure of quinolones. This protocol is simple and easy to handle. [Copyright &y& Elsevier]

Inexpensive and easily available unsaturated olefins as starting compounds, wide functional group tolerance, and atom economic conditions are key features of this reaction. [ABSTRACT FROM AUTHOR]
