Phenylsulphonylnitromethane (1) is C-alkylated by benzylic halides and primary alkyl iodides affording α-nitro-sulphones in 43–75% yield; α-nitro-sulphones (83–90% yield) are also obtained from the corresponding C-alkylation of allylic acetates in the presence of catalytic Pd(PPh3)4.
The first electrophilic Pd(II)-catalyzed allylic C H alkylation is reported, providing a novel method for formation of sp3-sp3 C C bonds directly from C H bonds. A wide range of aromatic and heteroaromatic linear (E)-alpha-nitro-arylpentenoates are obtained as single olefin isomers in excellent yields directly from terminal olefin substrates and methyl nitroacetate.
