The nitroolefin (NPP) efficiently transfers a 2-nitroallyl group even to the most reactive nucleophilic centres of organolithium reagents to give the products of type listed in the table.

The addition of the copper-zinc reagents RCu(CN)ZnX to a variety of nitro olefins produces polyfunctional nitroalkanes in high yields. The intermediate zinc or copper nitronates can be directly submitted to a Nef reaction (O3,-78-degrees-C) and converted to polyfunctional ketones in a one-pot procedure. The addition of RCu(CN)ZnX to nitro olefins bearing a leaving group (RSO2, RS) in the beta-position provides pure (E)-nitro olefins in excellent yields. The reaction has been applied for the stereoselective preparation of 1,3-nitrodienes and for a Diels-Alder reaction precursor.
