The invention relates to disubstituted-aminodifluorosulfinium salts represented by the formula (I). Processes for preparing same and methods of use as deoxofluorinating reagent is also provided.
The synthesis of N,N-disubstituted aminodifluorosulfinium tetrafluoroborate salts is reported, and their behavior as deoxofluorinating agent was evaluated. The deoxofluorination reactions were performed using a primary alcohol, a secondary alcohol and a ketone. Results show that subtle modification of the structure of the reagents can noticeably affect the reactivity and the selectivity in deoxofluorination
