A general method for synthesizing bifunctional hydroxamic acids containing carboxylic acid or amino functionalities is reported. Various products from simple alkyl to complex dendrimer-like structures are described. Such molecules have recently been used in ligand-exchange reactions for the hydrophilic stabilization of originally oleic acid protected iron oxide nanoparticles.
