Basic hydrogen peroxide and sodium perborate were found to be cheap and efficient alternatives for the conversion of primary and secondary nitro to carbonylcompounds (Nef reaction) in ionic liquids.
stereoselective synthesis of a variety of β-nitro-α-amino carboxylic acidsvia aza-Henry (nitro-Mannich) reaction of aldimines is disclosed, yielding either anti- or a rarely reported syn-configuration. The reaction operates directly on free glyoxylic acid and generates imine species in situ. Crystallization-controlled diastereoselectivity enables isolation of the target compounds in high enantio- and diastereomeric

Various nitro compounds were effectively reduced by sodium hydrogen telluride in good yields. Thus, reductive conversion of unhindered nitrobenzenes to azoxybenzenes, sterically hindered nitrobenzenes to anilines, nitroalkanes to dimer of nitrosoalkanes, and vicinal-dinitroalkane to olefin was achieved.

A survey of substitutionreactions conducted in a phosphoniumbistriflimideionicliquid is presented. The results demonstrate high selectivity favoring substitution over typically competitive elimination and solvolytic processes even when challenging secondary and tertiary electrophiles are employed. The first reports of Kornblum substitutionreactions in an ionicliquid are described that proceed
