General description

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for energy efficiency. Find details here.

Application

Nanocrystalline superlattices in gold colloid solution have been prepared by ligand-induction using AuCl3 reduced with sodium borohydride. Nucleophilic addition of hydride ion from sodium borohydride is an inexpensive alternative method for the Baylis-Hillman reaction to form [E]-a-methylcinnamic acids. A reductant solution composed of NaBH4 and NaOH was used to form mercury cold vapor. NaBH4 may be used to generate hydrogen by catalytic hydrolysis.
