Application of 2689-65-8. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: 5-Iodo-2-furaldehyde, is researched, Molecular C5H3IO2, CAS is 2689-65-8, about Stereospecific Synthesis of Tri- and Tetrasubstituted α-Fluoroacrylates by Mizoroki-Heck Reaction. Author is Rousee, Kevin; Bouillon, Jean-Philippe; Couve-Bonnaire, Samuel; Pannecoucke, Xavier.
Ligand-free, efficient, palladium-catalyzed Mizoroki-Heck reaction between Me α-fluoroacrylate and arene or hetarene iodides is reported for the first time. The reaction is stereospecific and provides fair to quant. yields of fluoroalkenes. The Mizoroki-Heck reaction starting from more hindered and usually reluctant trisubstituted acrylate, to access tetrasubstituted fluoroalkenes, is also reported. Finally, the use of a three-step synthesis sequence, including Mizoroki-Heck reaction, allows the synthesis of fluorinated analogs of therapeutic agents with high yield.
