Abstract

Studies of $^1H$ and $^{13}C$ chemical shifts and of $^1H-^lH$, $^{l3}C-^1H$ coupling constants of 1,3-di-(2-pyridyl)- thiourea and its substituted derivatives indicate the occurrenceof topomerisation between two internally hydrogen-bonded conformers, with a Z,E \rightleftharpoons E,Z interconversion barrier of ca. $55.0 kJ mol^{-l}$.
