Description:Substituted heterocycles are prevalent in natural products\, ph
 armaceuticals\, and agrochemicals\, especially those with sulfonyl-\, sulf
 oxyl-\, and alkyl-containing substituents. Due to their high oxidation pot
 ential and propensity for catalyst poisoning\, the C(sp2)-H functionalizat
 ion of N-heterocycles can be challenging. Pyridinium salts has been pivota
 l in recent light-promoted methods involving electron donor-acceptor (EDA)
  complexes\, as they negate the need for expensive\, tailor-made photocata
 lysts and have been used in the 3-chlorination of quinoxalinones. I propos
 e utilizing the redox capabilities of pyridinium salts through these EDA c
 omplexes to create a general platform for the sulfonation\, sulfoxidation\
 , and alkylation to a variety of hard-to-oxidize heterocycles. 4:00 pm
