Thermal decomposition of aromatic and heteroaromatic thioureas in boiling chlorobenzene is a first-order reaction. The reaction involves intramolecular hydrogen transfer followed by a cleavage of the C - N bond which is the rate-limiting step. The rate constants of decom position have been determined and correlated with quantum-chemical reactivity indices.
