In this study, a nucleophilic vinylic substitution reaction was developed to efficiently synthesize trisubstituted alkenes with stereocontrol under simple conditions. Additionally, dimerization of monofluoroalkenes to form (E,E)-divinyl ethers was observed, triggered by adventitious water in the reaction mixture.
We herein describe a nucleophilic vinylic substitution (SNV) of trisubstituted monofluoroalkenes with excellent stereocontrol (d.r. > 99:1). Starting from (E)-beta-monofluoroacrylates, various trisubstituted (E)-alkenes containing O/N/S-substituent groups at the vinylic position can be obtained under simple conditions. Furthermore, (E,E)-divinyl ethers can be generated through dimerization of the monofluoroalkenes, triggered by adventitious water in the reaction mixture.
