FeCl3ATMSCl: An effective catalytic system for the conjugate addition of sodium p-toluenesulfinate to αβ-enones
A new protocol for the β-sulfonation of αβ-unsaturated carbonyl compounds is described. The method employs FeCl3 as catalyst and TMSC1 as additive for conjugate addition of sodiump-toluenesulfinate to enones.
