Instead of an anionic donor that provides a hydride to a carbonyl, NADH is actually a neutral donor. The trans isomers and the cis isomers are identical if the two substituents are the same. 12 depicts the ionization process using electrons (referred to as electron impact (EI) mass spectroscopy). Addition of a hydride anion (H:-) to an aldehyde or ketone gives an alkoxide anion, which on protonation yields the corresponding alcohol. H- (NaBH4 or LiAlH4)||Aldehyde. Sodium borohydride is an inorganic compound whose chemical formula is NaBH4. The analytical detection of BH4 − using iodometric titraton must be abandoned altogether as it gives erroneously high concentrations, as high as eight times higher than the actual concentration of BH4 − in the samples.

Cooper, H. Electrolytic Process for the Production of Alkali Metal Borohydrides. However, semi-anionic compounds like sodium borohydride don't exist in the cell. Figen, A. ; Pişkin, S. Microwave assisted green chemistry approach of sodium metaborate dihydrate (NabO2·2H2O) synthesis and use as raw material for sodium borohydride (NaBH4) thermochemical production. This preview shows page 1 - 4 out of 8 pages. Gas chromatography analysis will be done to analyze the stereochemical distribution of products (cis versus trans) generated in the reaction. Metals 2019, 9, 1061. Sample Preparation and Injection. For monosubstituted cyclohexanes (cyclohexanes with one substitutent), one of the chair conformations has the substituent in an "axial" orientation that creates steric strain energy. The formulae of the two compounds are LiAlH4 and NaBH4. There are potentially four stereoisomers for each positional isomre if the two are different. 5 mmol sodium borohydride.
