The dramatic changes that have taken place in synthetic chemistry are a direct result of improved instrumentation for structural analysis of complex organic molecules. As instrumentation evolved from ultraviolet to infrared to proton nuclear magnetic resonance spectroscopy, it was the synthetic community that was first to develop and then to exploit the full power of each new technique. This does not appear to be the case with the latest tool, 13C NMR. spectroscopy, which has yet to find significant usage by synthetic chemists other than as a rather complicated means for counting carbons. The power of the technique is far greater than as a replacement for elemental analysis and indeed can be used to solve complicated structural problems more readily than less straightforward methods such as 2-D 1 H NMR. techniques.
