Environmentally sustainable: Glycerol- boric acid, good promoter in various organic synthesis due to green and mild catalytic properties

Abstract

Glycerol is a colorless, odourless and viscous liquid. It is a simple trihydric alcohol. Glycerol is widely used as a solvent because it enhances the rate of an organic reaction. Glycerol can be considered as ‘organic water’. Glycerol form strong hydrogen-bond, which facilitate it to dissolve a wide range of organic and inorganic compounds into it. Boric acid is a weak acid, its complex with polyhydroxy compounds is stronger due to chelate formation and it increases the acidity of the medium by the release of H⁺ ions.
