Abstract

Three types of organic solid-state reactions, dimerizations, dissociations, and Z-E isomerizations were investigated byusing the transformations of aromatic C-nitroso compounds incrystalline solids as a convenient molecular model. Here wepropose a conceptual frame for solid-state organic reactionmechanisms by examining activation parameters obtainedfrom kinetic measurements under specific experimental conditions.The possibility of the appearance of a sort of short-livedintermediate liquid phase that constitutes a critical conditionfor initiating chemical reaction in crystalline solids, similarly tothe mechanism for the thermal solid-state reactions proposedby Paul and Curtin is discussed. The analogy of the proposedconcept with the recent hypothesis about the variable rigidity/softness of the reaction cavity in the enzyme reactions, andwith the newest molecular dynamic simulation studies of solidphase transformations was considered.
