PREPARATION OF BIS(FLUOROALKYLENESULFONYL)IMIDES AND (FLUOROALKYLSULFONYL) (FLUOROSULFONYL)IMIDES

摘要

A method for preparing fluoroalkylsulfonyl imides by reacting a fluoroalkylsulfonamide with a fluoroalkylsulfonyl halide or a fluorosulfonyl halide in the presence of a non-nucleophilic base. One reaction is:Z-Rf-SO2NH2+Z-R'f-SO2-X+2B+Z (Z-Rf-SO2)(Z-R'f-SO2)N-.BH++BHX,where each Z is a fluorine atom or a polymerizable organic functional group, Rf and R'f are fluoroalkylene groups optionally containing catenary oxygen or nitrogen, X is a halogen atom, and B is a non-nucleophilic base. Unsymmetrical imides and polymeric imides can be prepared.
