小注:

Reagent for high yield, low racemisation peptide coupling[1], mild and efficient reagent for the preparation fo esters from carboxylic acids and alcohols[2]; for esterification of amino at low temperature[3], for use in formation of mixed phophonate diesters[4]. The carboxyphosphonium salts formed by reaction with carboxylic acids can be reduced with NaBH4, providing a mild method for reduction of acids to alcohols[5]. Promotes the reaction of aliphatic primary amines with CS2 to give isothiocyanates which can be isolated in high yield or reacted in situ with nucleophiles[6].
