Xu, Xiao published the artcileVisible light-promoted umpolung coupling of aryl tri-/difluoroethanones with 2-alkenylpyridines, SDS of cas: 5860-95-7, the publication is Chemical Communications (Cambridge, United Kingdom) (2018), 54(78), 11017-11020, database is CAplus and MEDLINE.
Using an umpolung strategy, herein the first intermol. reductive cross-coupling of aryl tri-/difluoroethanones with 2-alkenylpyridines with the aid of a Bronsted acid catalyst upon visible-light irradiation is reported. This metal-free reaction is operationally simple and performed at ambient temperature, allowing access to desired tertiary alcs. with tri-/difluoromethyl groups in moderate to excellent yields. The com. available and easily handled Hantzsch ester effectively serves as an electron donor, as well as a hydrogen atom source.
