An organometallic substitute for the radioactive Bolton–Hunter reagent
Abstract
Novel organometallic reagents, such as the stable cobalt and molybdenum carbonyl complexes of hex-4-ynoic acid N-hydroxysuccinimide ester which are detectable at very low concentrations by Fourier transform infrared spectroscopy, couple with amine residues of peptides under mild conditions and provide a non-radio isotopic alternative for the widely used radioactive Bolton–Hunter tracer.
