Zhang, X.; Sun, G.; Hinrichs, K.; Janietz, S.; Rappich, J.: Infrared spectroscopic study of the amidation reaction of aminophenyl modified Au surfaces and p-nitrobenzoic acid as model system. Physical Chemistry Chemical Physics 12 (2010), p. 12427-12429

We have investigated the fundamental amidation reaction by a model system consisting of an electrochemically functionalised Au surface by aminophenyl and 4-nitrobenzoic acid activated by EEDQ. The development of the NO2 related stretching vibrations with time reveals that the amidation process is very slow at Au surfaces and is completed after about 2 days.
