Regioselective Preparation of Allylic Sulfones by Palladium-Catalyzed Reactions of Allylic Nitro Compounds with Sodium Benzenesulfinate
Treatment of allylic nitro compounds with sodium benzenesulfinate in the presence of 5 molpercent of Pd(PPh3)4 in N,N-dimethylformamide (DMF) at 20-70 deg C for 1-10 h resulted in the formation of allylic sulfones with predominance of kinetically controll
REGIOSELECTIVE SYNTHESIS OF ALLYLIC SULFONES BY PALLADIUM-CATALYZED DENITRO-SULFONYLATION OF ALLYLIC NITRO COMPOUNDS
Allylic nitro compounds undergo denitro-sulfonylation catalyzed by Pd(PPh3)4 or Pd(PPh3)4+NaNO2 with PhSO2Na*2H2O to afford allylic sulfones regioselectively.
