Abstract

This communication presents the synthesis and the characterization of new organic molecules bearing up to three N-phenyl-oxalamic acid ethyl esters. The syntheses are based on Sonogashira-type cross-coupling reactions with preformed oxalamic ester intermediate building blocks. The short synthetic pathways lead easily to valuable potential oxamato-bridging ligands with overall interesting yields.
