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

摘要

A method for preparing fluoroalkylsulfonyl imides by reacting afluoroalkylsulfonamide with a fluoroalkylsulfonyl halide or afluorosulfonyl halide in the presence of a non-nucleophilic base. One reactionis: Z-R s-SO2NH2 + Z-R'f-SO2-X + 2B ~ (Z-R f-SO2)(Z-R'f-SO2)N-.cndot.BH+ + BHX, where each Z is a fluorine atom or a polymerizableorganic functional group, R f and R'f are fluoroalkylene groupsoptionally containing catenary oyxgen or nitrogen, X is a halogen atom, and Bis a non-nucleophilic base. Unsymmetrical imides andpolymeric imides can be prepared.
