Abstract

The thermally activated NH→ CH tautomerization process in crystals of 2 (2, 4-dinitrobenzyl) pyridine derivatives was investigated. The results indicate the absence of any trivial molecular structure–reactivity correlation, in contrast to what is found for similar systems in solutions. The absence of molecular structure–reactivity correlation in the crystalline state is attributed to the participation of neighboring molecules in the proton transfer process. A ...
