The solid-state thermal polymerization of crystalline 2,4-hexadiyne-1,6-diol bis-(p-toluenesulfonate) (PTS) was investigated by solid-state 13C NMR, the first application of this technique to such a process. The kinetics of the thermal process was ex

While p-ethynylbenzoic acid (EBA) has been suggested to be reactive in the solid state, the structure−reactivity relationships and the nature of the product(s) have remained unknown. Crystallized f...
