Direct isoperfluoropropylation of arenediazonium salts with hexafluoropropylene†
Abstract
An efficient copper-promoted isoperfluoropropylation of aryl diazonium salts is described. The reaction occurs under mild conditions using commercially available hexafluoropropylene (HFP) as the starting material. In addition, a one-pot direct diazotization and isoperfluoropropylation protocol was developed. The method allows facile conversion of various arylamines into isoperfluoropropylarenes with good functional group compatibility using HFP.
