Alkyl Transfer from C—C Cleavage: Replacing the Nitro Group of Nitro-Olefins.

Alkyl substituted Hantzsch esters are rationally used as alkylation reagents to replace the nitro groups of nitro olefins to give excellent yields of trans-olefins. The reaction mechanism is considered to proceed through a free radical mechanism, which is different from the corresponding transfer alkylation of imines.
