Understanding the strategy of fluorination to control π-conjugation and intra interchain interactions for rational design improved semiconducting polymers.

Herein we report the deoxygenated fluorination of readily available carboxylic acids. A series acyl fluorides have been synthesized using shelf-stable N -trifluoromethylthiophthalimide as a fluorinated reagent for first time.

A scalable, efficient and safe electrochemical fluorination protocol is conferred. broad range of iodine(iii) mediated transformations were performed in high yields without exposure to toxic HF.
