Addition of silver nitrite to 2-bromoalkyl phenyl selenide in the presence of mercury(II) chloride afforded 2-nitroalkyl phenyl selenide, which upon oxidative deselenenylation provided the conjugatednitroalkene in excellent yield.

Mono-β-substituted conjugatednitroalkenes are readily reduced by zinc borohydride in 1,2-dimethoxyethane to the corresponding nitroalkanes, whereas the disubstituted ones furnish the corresponding oximes in excellent yields.

highly enantioselective (>/=92% ee) catalytic method for conjugate addition of alkylzinc reagents to cyclic nitroalkenes is reported. Reactions are promoted in the presence of 0.5-5 mol % (CuOTf)2.C6H6 and 1-10 mol % of chiral amino acid-based phosphine ligands at 0 degrees C in toluene. The Cu-catalyzed reactions can be effectively carried out with small-, medium-, and large-ring nitroalkenes. Depending
