Abstract

Facile nucleophilic attack on coordinated carboxylate ligaods is reported: complexes of tantalum(V) react rapidly with amines and amino acid esters to give the corresponding amides. Cyclopentadienyltantalum(V) amino acid carboxylate complexes have been prepared and reacted with free amino acid esters to give dipeptides in good yield and with high stereochemical purity.
