Palladium-catalysed arylation of sulfonamide stabilised enolates
摘要:
alpha-Arylation of inethanesulfonamides using palladium catalysis is described. For example, treatment of N-benzyl-Nmethylmethanesulfonamide with catalytic Pd(OAc)(2) in the presence of sodium tert-butoxide, triphenylphosphine and toluene afforded N-benzy]-N-methylphenylinethanesulfonamide in 66% yield.
