has been used to prepare a newclass of tetradentate bis(amino-oxazoline). The reaction between 2,2‘-diaminobiphenyl and 1 equiv of 2-(2‘-bromophenyl)oxazoline is highly selective for monoarylation, and the resulting products have been reacted in a second arylation to afford unsymmetrically substituted bis(amino-oxazolines). These new diamido/donors belong to the tropos class of ligand and exist as an
