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.
Direct Conversion of Allylic Nitro Compounds into Allyl Sulphides and Allyl Sulphones
Allylic nitro compounds are directly converted into allyl sulphides or allyl sulphones with high regioselectivity on treatment with sodium benzenethiolate alone or with sodium benzenesulphinate in the presence of a catalytic amount of Pd(PPh3)4.
