Echemendia, Radell; de Oliveira, Kleber T.; Burtoloso, Antonio C. B. published the artcile< Visible-Light-Promoted Synthesis of 1,3-Dicarbonyl Sulfoxonium Ylides>, Recommanded Product: (E)-Cinnamoyl chloride, the main research area is dicarbonyl sulfoxonium ylide green preparation; diazoketone sulfoxonium ylide coupling visible light promoted.
A novel visible-light-promoted synthesis of 1,3-dicarbonyl sulfoxonium ylides I [R = Ph, 2-ClC6H4, 4-MeC6H4, etc.; R1 = Ph, 4-MeOC6H4, 4-O2NC6H4, etc.; R2 = H, Me] via coupling of diazoketones with sulfoxonium ylides was described in both batch and continuous flow conditions. This transformation permitted the direct synthesis of synthetically useful 1,3-dicarbonyl sulfoxonium ylides I (33 examples, 21-85% yields), by means of an acylation reaction from the in situ and selective generation of ketenes. The reaction performed under flow conditions proved to be very efficient, providing the 1,3-dicarbonyl sulfoxonium ylides with higher yields and shorter reaction times.
