25 The combination of NaBH4 with carboxylic acids results in the formation of acyloxyborohydride species, such as stab.

The mechanism of ketone and aldehyde reduction has been scrutinized by kinetic studies, and contrary to popular depictions in textbooks, the mechanism does not involve a 4-membered transition state like alkene hydroboration, 16 or a six-membered transition state involving a molecule of the alcohol solvent.The same reaction can run also intramolecularly: an -ketoester converts into a diol, since the alcohol produced will attack the borohydride to produce an ester of the borohydride, which then reduces the neighboring ester.A Recycling Hydrogen Supply System of NaBH4 Based on a Facile Regeneration Process: A Review.Low and Bansal, 2009 Stuart Gary, " Hydrogen storage no longer up in the air " in ABC Science, citing Christian, Meganne; Aguey-Zinsou, Kondo François (2012).This reaction is used in the production of various antibiotics including chloramphenicol, dihydrostreptomycin, and thiophenicol.18 19,-Unsaturated ketones tend to be reduced by NaBH4 in a 1,4-sense, although mixtures are often formed.
