High volume hydrogen production from the hydrolysis of sodium borohydride using a cobalt catalyst supported on a honeycomb matrix

“…In order to avoid this deactivation process an initial NaBH 4 concentration lower than 16 g in 100 g of water is generally used [10,15]. A number of studies have been published dealing with both the catalytic activity and long-term stability of Co 2 eB catalysts doped with either Cr or W [1,4,5,7,13,16,17]. Cobalt oxides have also been extensively studied [14,18,19] Several types of reactors, both static and dynamic have been designed to exploit the SBH reaction.…”

Thirty Six Years of Research on the Selective Reduction and Hydroboration

“…However, the discovery of sodium borohydride 99 in 1942 and of lithium aluminum hydride 100 in 1945 brought about a revolutionary change in procedures for the reduction of functional groups in organic molecules. Today, for instance, in dealing with the problem of reducing an aldehyde or ketone function, the synthetic organic chemist will rarely undertake to use such a conventional technique.…”

Simple reduction of ethyl, isopropyl and benzyl aromatic esters to alcohols using sodium borohydride-methanol system

“…The alcohols obtained from benzilic esters were purified by column chromatography on silica gel, eluting with hexane:ethyl acetate gradient (up to 50%) afforded the pure derivatives 24, 27, 30, 33, 36, 39, 42, 60 and 64. All the alcohols were fully characterized by CG-MS, 1 H and 13 C RMN spectra and are known in the literature 10 .…”

“…One of the most common reagent used for this purpose is sodium borohydride. 1 Usually, the reactions carried out with NaBH 4 are safe, inexpensive and can be done in mild conditions. 2,3 Although this reducing agent has been constantly used for reduction of aldehydes, ketones and other important functional groups, it is not common to use NaBH 4 itself for reduction of esters.…”
