Tae Seop Uhn*, Jong Pal Lee, Hyun Seok Park, Hyung Tae Kim, Zoon Ha Ryu
The reactions of alkanesulfonyl chlorides with pyridines in the presence of various solvents have been studied by means of kinetic method. Alkanesulfonyl chlorides bearing α-hydrogen with the normal attack of pyridine is found to be at the α-hydrogen with elimination to form the sulfene intermediate evidently. From the mass spectra by the reaction of ethanesulfonyl chloride with 3-picoline in the presence of methanol-d1, it has shown that the reaction has a witness favorable to the slulfene intermediate.
