We have developed a highlyefficient method for the copper-catalyzed amidation of aldehydes in the presence of N-bromosuccinimide (NBS). This method is simple, economical, and has practical advantages for synthesis of imides.
The first approach to α-fluorination of aroylacyl imides without a catalyst was accomplished, relying on electrophilic activation through the reaction between a fluoride salt, dimethylsulfoxide and an imide. The synthesis of α-fluorinated aroylacyl imides in good yields was achieved using inexpensive reagents such as NaF and DMSO.
