Optimization of reaction conditions required accurate determination of concentrations of all products. (A) Structures of quantified compounds and their retention times. (B) High-performance liquid chromatography traces of standard mixtures at five different concentrations (0.3−5.0 mM) with a UV detector set to 254 or 220 nm. Compounds 2 and 7 do not have a strongly absorbing chromophore at 254 nm. (C) We determined the conversion factor between absorbance and concentration for each component from the range with linear dependence of absorbances on concentration as the slope of the line with forced zero crossing.
