Reductions of esters, acyl halides, alkyl halides, and sulfonate esters with sodium borohydride in polyethylene glycols: Scope and limitation of the reaction
Sodium borohydride in ethylene glycol oligomers (PEGS) has been explored as a novel reducing system for esters, acyl chlorides, alkyl halides, and sulfonate eaters. The selectivity of the system is exemplified by its inertness toward nitrogen-containing functional groups such as amides, azides, nitriles, and nitroalkanes. Both hydroxy groups of the oligomeric diols have been established to be necessary for the above reducing system. The nature of ...
