β¦ Synopsis
Analysis of the temperature dependence of the electron spin resonance spectra of 4_cyanopyridine-potassium in 1, Z-dimethoxyethaze reveals the presence in solution of two species in thermodynamic equilibrium, The rate of interconversion
Between the two species is relatively slow.

## Abstract We report herein the kinetic studies on hydrolysis of three cyanopyridines in highβtemperature water. 3βCyanopyridine, 4βcyanopyridine and 2βcyanopyridine underwent consecutive hydrolysis to the corresponding pyridinecarboxamides and picolinic acids. Further decarboxylation to pyridine
