Sodium trimethoxyborohydride, lithium borohydride, sodium borohydride and lithium aluminum hydride are satisfactory reducing agents for converting conjugated nitroalkenes to their corresponding nitroalkanes. The reduction reactions are accompanied by consecutive processes in which the initial reduction products add to the parent nitroolefins to give salts of the corresponding 1, 3-dinitroalkanes and related polynitroalkanes of higher molecular ...
