p-Quinodimethanes (p-QDM’s) are reactive, cross conjugated cyclic molecules that have been invoked as transient intermediates in a number of reactions and interesting fundamental molecules. Commercially useful polymers have been developed from p-QDM’s. p-Diphenoquinodimethane is highly reactive and has been proposed as an intermediate in several reactions. Details of our preparation and characterization of precursor compounds and attempted observation of p-Diphenoquinodimethane by 1H NMR spectroscopy will be presented.
