Liquid Crystalline Catalysis. 2. Sulfonate Ester Rearrangements Induced in Solution by the Ordered Structure of a Smectic B Solvent
We have used a smectic B (Sm B) solvent to obtain experimental evidence of the catalytic effect of tightly ordered mesomorphic structures.To accomplish this we have selected two reactions with severe orientational demand in the transition state.The liquid

Thermal solid-state reaction of methyl p-dimethylaminobenzenesulfonate to p-trimethylammoniumbenzenesulfonate zwitterion: Optical crystallographic studies
The thermal isomerization reaction from methyl p-dimethylaminobenzenesulfonate (MSE) to p-trimethylammoniumbenzenesulfonate zwitterion (ZWT) in the crystalline state has been studied by optical crystallographic methods. Clear evidence of the lattice trans
Evidence of a lattice instability during the thermally enhanced reaction of MSE studied by calorimetry, 13C-NMR, Raman scattering and birefringence
A methyl p-dimethylaminobenzenesulfonate (MSE) polycrystalline powder or single crystal is converted to the zwitterionic product p-trimethylammonium benzenesulfonate (ZWT) by a chemical thermally induced reaction. This reaction is associated to a first-or
SURFACE VS. BULK REACTIVITY IN A SOLID-STATE METHYL TRANSFER
A methyl transfer in the crystalline state proceeds more slowly at the surface (as monitored by diffuse reflectance IR), than within the bulk solid (as monitored by NMR).Moreover, reaction intermediates accumulate only at the surface.These results are exp
