Cobalt(II)-porphyrin complex 1 and 2 catalyses the chlorination and sulfochlorination respectively of n-alkanes and cycloalkanes with sulfuryl chloride in benzene.The p-substituent of the benzene ring in the porphyrin complex 1 and 2 shows a remarkable chemoselectivity in these reactions.

Sulfuryl chloride has been tested as a chlorosulfonation reagent of n-heptane under various conditions.Pyridine was confirmed as the best catalyst for the reaction and the sulfochlorination yield was found to be enhanced by the use of benzene as solvent.The distribution of all the isomeric chlorinated and sulfochlorinated products has been measured.This information is used in order to understand the mechanism of this rather complex reaction.The catalyzed photoinitiation leads to the in situ formation of a low concentration of molecular chlorine.The observed selectivity is the result of a delicate balance between the photoinitiation leading the chlorine atoms and the rather short chain propagations leading to the formation of the chlorosulfonyl radical.
