Description

Application

Benzyltrimethylammonium bromide (BTMAB) can be used as a starting material for the synthesis of benzyltrimethylammonium fluorochromate (BTMAFC) by treating with an aqueous solution of CrO₃ and HF. BTMAFC can be utilized as an efficient oxidizing reagent for the selective oxidation of oximes into ketones or aldehydes, and primary, secondary, allylic as well as benzylic alcohols to their corresponding carbonyl compounds.

BTMAB can be also used as:      

• An oxidizing reagent for the conversion of monosubstituted benzylamines into corresponding aldimines in the presence of DMSO.      
• A benzylating reagent for the benzylation of aryl amide C-H bond using Ni catalyst.
