Abstract:

The reduction of aromatic nitro compounds to corresponding azoxy compounds with sodium borohydride was catalyzed by BiO(OH)/actived carbon (AC), which was prepared by equivalent-volume impregnation. The influences of catalyst, sodium borohydride and sodium hydroxide amount were investigated with 10 mmol of nitrobenzene as substrate in methanol at room temperature. The suitable reaction conditions are as follows: 0.2 g of catalyst, 10 mmol of sodium borohydride and 0.1 g of sodium hydroxide. Under the conditions, the seven aromatic nitro compounds were reduced to corresponding azoxy compounds w

Abstract:

The recycling of sodium borohydride poses a huge challenge to the drive towards a hydrogen economy. Currently, mechano-chemical, thermo-chemical and electrochemical are the only reported methods of recycling sodium metaborate into sodium borohydride. Much attention has been devoted to the mechano-chemical and thermo-chemical methods of reduction, but little focus has been devoted to electrochemical methods. This review describes the electrochemical behaviour of borohydride (BH4−) and metaborate (BO2−) anions in alkaline solutions. The BH4− is stabilized in highly concentrated alkaline solution

A simple and efficient method for chemoselective deallylation of –COO-allyl group in presence of C-allyl group has been developed.

The reagent's stability, ready availability and ease of handling encourage its usage for deallylation. KEY WORDS: C-allyl cleavage, Sodium borohydride, Chemoselectivity, Reduction Bull. Chem. Soc.

Abstract:

The synthesis of disecondary aromatic diols (the main precursors for divinyl aromatic monomers) was carried out. The optimal conditions for the preparation of these diols by selective catalytic hydrogenation of aromatic diketones in the presence of Raney nickel and by reduction of these diketones by sodium borohydride were established. It was demonstrated that sodium borohydride reduction afforded the pure diols under mild and relatively safe conditions (in the systems of CHCl3–PEG400–H2O, at room temperature and atmospheric pressure).

Followed by reduction with sodium borohydride-iodine in tetrahydrofuran, we synthesized the target compound. We used IR spectra to study the process of the reduction and modified the reaction conditions. It is the first time we reported (S)-1-benzyl-3-pyrrolidinol-borane which is the intermediate of the reduction with sodium borohydride-iodine system, and its spectral dat

Abstract:

Regioselective reactions can play pivotal roles in synthetic organic chemistry. The reduction of several 1-substituted 1,2,3-triazole 4,5-diesters by sodium borohydride has been found to be regioselective, with the C(5) ester groups being more reactive towards reduction than the C(4) ester groups. The amount of sodium borohydride and reaction time required for reduction varied greatly depending on the N(1)-substituent. The presence of a β-hydroxyl group on the N(1)-substituent was seen to have a rate enhancing effect on the reduction of the C(5) ester group. The regioselective reduction was at

Abstract:

A solid-state NaBH4/Co composite has been employed as a hydrogen-generating material, as an alternative to sodium borohydride solutions, in the long storage of hydrogen. Hydrogen generation begins in the presence of cobalt-based catalysts, immediately after water is added to a NaBH4/Co composite, as a result of sodium borohydride hydrolysis. The hydrogen generation rate has been investigated as a function of the pressure used to press hydrogen-generating composites from a mechanical mixture of the hydride and cobalt chloride hexahydrate.

Abstract:

Borohydride reduction of titled ketones 1a-1g gave diastereoisomeric mixtures of (Z)-1,3-diphenyl-3-(2-phenylimidazo[1,2-a]pyridin-3-yl)prop-2-en-1-ols 2a-2g and 3a-3g in which the former ones prevailed. Only individual racemic products were obtained after borohydride reduction of (E)-1,3-diphenyl-3-(2-phenylimidazo[1,2-a]pyridin-3-yl)-prop-2-en-1-one 4 to corresponding 1-hydroxy derivative 5 and by conversion of (Z)-1-oxo derivative 1a to 1,3-diphenyl-3-(2-phenylimidazo[1,2-a]pyridin-3-yl)propan-1-one (6) with sodium hydrogenselenide. Diastereoselectivity of the borohydride reduction is discu

Abstract:

AbstractWe propose a new method for preparing atom probe tomography specimens from nanoparticles using a fusible bismuth–indium–tin alloy as an embedding medium. Iron nanoparticles synthesized by the sodium borohydride reduction method were chosen as a model system. The as-synthesized iron nanoparticles were embedded within the fusible alloy using focused ion beam milling and ion-milled to needle-shaped atom probe specimens under cryogenic conditions. An atom probe analysis revealed boron atoms in a detected iron nanoparticle, indicating that boron from the sodium borohydride reductant was inc
