In the presence of large excesses of borohydride salts, gold monolayer protected-clusters can be grown to larger sizes simply by controlling the amount of reducing agent added to smaller clusters. In addition, gold monolayer clusters can be used as catalysts for reduction reactions by sodium borohydride; results suggest such catalysts have sterically constrained active sites.

The dehalogenation of a-haloketones and a-halocarbonyl compounds is an inevitable proce­ dure for the organic synthesis and these reductive dehalogenations have been often effected in organic syntheses. There have been various procedures for the purpose and these are obtained by zinc and acetic acid [1], sodium dithionite [2], titanium(III) chloride [3], organotin hydride [4], sodium hydrogen t...

Polyaniline and polyamide (nylon 6,6) nanocomposites with Silva were prepared by in-situ oxidativepolymerization of aniline monomers in the presence of Ag salt Nano particles of silver (NPs) were symthesieedby controlled reduction of Ag+ ions kith sodium borohydride at room temperature. Nylon 6,6 wax loaded withAg nanoparfieles by erdrapment of Ag+ ions into the polymer network, followed by red...

Reduction of virginiamycin S with sodium borohydride produces allo- and normal-dihydro-virginiamycin S. Reduction of the tosylhydrazone of virginiamycin S with sodium cyanoborohydride affords deoxyvirginiamycin S. These compounds are less active than virginiamycin S. Like virginiamycin S they enhance the activity of virginiamycin M1.

The reactivity of sodium borohydride in the presence of other species has been examined by adiabatic calorimetry. In combination with water, sodium borohydride exhibits an exotherm at room temperature accompanied by generation of gas (presumed to be hydrogen). Addition of potassium hydroxide to a sodium borohydride-water mixture is found to stabilize the solution and require a higher temperatur...

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