(sp3) coupling; deaminativecoupling; Katritzky salt; photoredox catalysis; Introduction
The selective formation of new carbon–carbon bonds via direct C–H functionalization bears the potential of being a process of high efficiency [1][2][3]. Since C–H bonds are omnipresent in organic compounds it is
demonstrate the deaminativecoupling of N-benzylpyridinium Katritzky salts with THIQs under ruthenium photoredox catalysis. During the preparation of this article, a similar transformation was disclosed using an iridium photoredox catalyst [47].
