Rongalite (sodium hydroxymethanesulfinate or sodium formaldehydesulfoxylate) reacts with organic halides in a variety of ways depending on the structure of the organic compound. Benzyl and other alkyl halides give sulfones in generally good yields; but in several cases, reduction (2, 4-dinitrobenzyl bromide, phenacyl halides) or coupling@-nitrobenzyl bromide under basic conditions, phenacyl bromide or iodide) of the halide occurs. Addition of ...
