| Application: | Boric acid can be used as a catalyst to synthesize: • N-substituted cinnamamides via amidation reaction between cinnamic acid and benzylamines. • β-Aminoalcohols through the regioselective epoxides ring opening with aromatic amines in the presence of glycerol as a co-catalyst. • Organosulfur compounds via thia-Michael addition of thiols to α, β-unsaturated compounds. It can also be used as an activator for the solvent-free reduction of aldehydes and ketones to alcohols in the presence of sodium borohydride. |
| General description: | Boric acid is a weak monobasic Lewis acid(electron pair acceptor), which finds application in the areas of glass making, fire retardant, lubrication agent, buffer, and neutron absorber. |
