Electrophilic Addition of XY Reagents to Alkenes and Alkynes

A Versatile Route to 2-Substituted Cyclic 1,3-Dienes via a Copper(I)-Catalyzed Cross-Coupling Reaction of Dienyl Triflates with Grignard Reagents

“…Conjugated dienes are versatile starting materials in organic synthesis and selective methods for their preparation are of continuous interest and related cycloadditions, together with some limited use in electrophilic addition reactions . More recently, however, there has been an increasing interest in the use of conjugated dienes in metal-mediated reactions. , …”

Mild, Efficient, and Metal-Free Radical 1,2-Dithiocyanation of Alkynes and Alkenes at Room Temperature

“…1−13 It has been widely studied and utilized in various techniques for functional group interconversions. 14−17 Difunctionalization of alkenes is an attractive method for introducing a set of groups during a one-pot reaction process. 18,19 Dithiocyanation of alkynes and alkenes is meaningful as they show fungicidal activity.…”

“…Difunctionalization of organic substrates is a powerful tool in modern organic synthesis, which mainly involves alkynes as well as alkenes in organic synthesis. − It has been widely studied and utilized in various techniques for functional group interconversions. − Difunctionalization of alkenes is an attractive method for introducing a set of groups during a one-pot reaction process. , Dithiocyanation of alkynes and alkenes is meaningful as they show fungicidal activity . In addition, different sulfur derivatives can be synthesized from the thiocyanates. − These can be easily converted to different compounds such as sulfides, disulfides, thioesters, thiols, thiocarbamates, and many sulfur heterocycles. − Therefore, efficient incorporation of the thiocyano group into organic molecules has drawn much attention.…”

Alkene selenenylation: A comprehensive analysis of relative reactivities, stereochemistry and asymmetric induction, and their comparisons with sulfenylation

“…Electrophilic addition to alkenes is one of the most fundamental, generalized, and versatile methods for selective functionalization of hydrocarbons [ 1 ]. Despite recent progress [ 2 – 3 ] in both synthetic and theoretical investigations of electrophilic selenenylation, it still remains one of the least studied types of electrophilic addition to alkenes, in particular when compared with sulfenylation.…”
