Winterson, Bethan; Rennigholtz, Tim; Wirth, Thomas published the artcile< Flow electrochemistry: a safe tool for fluorine chemistry>, Category: esters-buliding-blocks, the main research area is fluoro compound preparation; allyl amide electrochem fluorination hypervalent iodine mediated; alc allyl electrochem fluorination hypervalent iodine mediated; carbonyl compound electrochem fluorination hypervalent iodine mediated.
A scalable, versatile and safe electrochem. fluorination protocol was conferred and strategy proceeded through a transient (difluoroiodo)arene, generated by anodic oxidation of an iodoarene mediator. Even the isolation of iodine(III) difluorides was facile since electrolysis was performed in the absence of other reagents. A broad range of hypervalent iodine mediated reactions afforded 5-(fluoromethyl)-aryl-oxazolines [R = Ph, 2-furanyl, 4-MeOC6H4, etc.], ((2,3-difluoropropoxy)methyl)-aromatic compounds [R1 = Ph, 2-MeC6H4, 4-FC6H4, etc.; R2 = H, Me] and some fluoro compounds R3-F [R3 = 1,3-diphenylpropanyl-1,3-dione, 1-phenyl-1-propanone, 3-phenyldihydrofuran-2(3H)-one, etc.] in high yields by coupling the electrolysis step with downstream reactions in flow, surpassing limitations of batch chem. (Difluoroiodo)arenes were toxic and suffered from chem. instability, so the uninterrupted generation and immediate use in flow was highly advantageous. High flow rates facilitated productivities of up to 834 mg h-1 with vastly reduced reaction times. Integration into a fully automated machine and in-line quenching was key in reducing the hazards surrounding the use of hydrofluoric acid.
