| Application: | • Boron trichloride, a Lewis acid, is a general reagent for the cleavage of a wide range of ether and acetal protecting groups. • It is a useful reagent to directly convert aromatic aldehydes to the corresponding gem-dichlorides. • It can also be used in the transmetallation reaction with less nucleophilic reagents such as tin and zirconium organometallic compounds to synthesize a variety of organoboranes. |
| Application: | For preparing methyl esters of fatty acids and for transesterification of triglycerides. |
