Abstract:
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.
