General description

Tributyl borate is an organoboron compound, that is often used as a reagent in organic synthesis for the preparation of various boronic acid derivatives, which are widely used in Suzuki coupling reactions in the synthesis of biaryls and other organic molecules. It is also used as a catalyst in a range of organic reactions, including the transesterification of esters and Biginelli reactions.

Application

Tributyl borate can be used as:    
  • A catalyst in the synthesis of dihydropyrimidinone derivatives via the Biginelli reaction.   
  • A boron oxide source to prepare carbon nanotube-B2O3 nanocomposite by solvothermal method.
