The Uses of Triphenylmethyl bromide

Reagent for the preparation of trityl esters.

The Uses of Triphenylmethyl bromide

It is considered as a more reactive reagent than Chlorotriphenyl-methane, for the preparation of trityl esters. It is also used in one-pot conversion of amino acids to their N-trityl derivatives involving N,O-ditritylation and selective methanolysis of the trityl ester.
