sulfa-Michael addition of nitroalkenes and thiols was investigated. The sulfa-Michael addition is kineticcontrol at the beginning and thermodynamiccontrol at the end for less bulky reactants. Thus, kinetic and thermodynamic-controlled adducts can be obtained as major products by controlling the reaction time in those cases. Linear nitroalkenes generally produce anti-adducts as major kinetic products due
