A highly enantioselective conjugate addition of arylboronic acids to cyclic as well as acyclic aromatic and aliphatic nitroalkenes is presented. The rhodium complexes obtained from deoxycholic acid-derived binaphthyl and flexible biphenyl phosphites showed good activity as well as very high enantioselectivity (ee up to 99%) in the conjugated addition even in the presence of challenging substrates such as 1-nitrocyclohexene or aliphatic acyclic nitroalkenes.

Palladium(II)-catalyzed Michael-type hydroarylation of nitroalkenes using aryltins and sodium tetraarylborates

A variety of aryltin compounds and sodium tetraarylborates can be employed for Michael-type hydroarylation reactions of nitroalkenes to afford β-arylnitroalkanes in moderate to good yields in the presence of either LiCl, MgCl2, or CaCl2 and a catalytic amount of palladium(II) salt (0.05 molar amount) in acetic acid. Results show that 50-70% of aryl groups out of all in these aryl compounds can be transferred to the products in this hydroarylation. The addition of a catalytic amount (0.05-0.10 molar amount) of a Lewis acid chloride, BiCl3 or SbCl3, much improves the product yield in some cases.
Conjugate addition of mixed diorganozinc compounds and functionalized organozinc cuprates to nitroolefins

equation presented The copper-catalyzed conjugate addition of symmetrical and mixed diorganozinc compounds as well as functionalized diorganozinc cuprates to nitroolefins leads to synthetically versatile nitro compounds in moderate to good yields. Mixed TMSM-organozinc compounds are suitable reagents for conjugate addition, since the TMSM group is not being transferred. Ipso substitution is observed in the absence of a catalytic amount of copper(I) salt. The nitroalkene moiety in 3-nitroacrylates proved to be the predominant Michael acceptor.
