The purpose of the Chemical Rediscovery Survey is to simply report what happens when (mainly simple organic) chemicals are mixed under controlled conditions. The behavior of these mixtures is primarily reported by H NMR using a co-axial system where the deuterated solvent needed to lock the NMR signal is placed in an outside chamber , thus preventing it from chemically interacting with the mixture under study. Since homogeneous solutions are typically required for high quality spectra and reliable integration, when insolubility events occur the experiments are stopped and the outcome reported. The ultimate aim of the survey is to uncover unexpected and potentially useful chemical behavior upon a systematic search of as much of the mole fraction hyperspace of a collection of simple and primarily safe chemicals.
Although concepts such as mechanisms, kinetics, the solute/solvent paradigm and other basic organic chemistry basic theory will be considered when potentially useful in reaction design, these will not be systematically considered a priori in the the selection of which chemical mixtures to explore. We believe that this bias has proven to act as a powerful conceptual barrier to attempting types of experiments which may lead to the discovery of new useful chemical behavior.
