TATU

 

 

 

 

 

 

 

TATU is a very efficient coupling reagent like HATU.  The different counter ions appear to have little or no effect on the rate of activation or on the yield of the coupling reaction.  TATU is highly effective for preparing carboxylic acid esters and primary alcohols, secondary alcohols or phenols (JD Twibanire, TB Grindley, Org. Lett., 2011, 13, 2988-91).
