A facile conversion of symmetrical to unsymmetrical thioureas

Unsymmetrically Substituted Thioureas. 1,1-Dimethyl-3-o-tolylthiourea and 1,1-Diethyl-3-o-tolylthiourea

“…The preparation of these compounds is described elsewhere (Ramadas, Srinivasan & Janarthanan, 1993). Single crystals suitable for X-ray study were obtained from ethanol solution on slow evaporation.…”

Symmetrically Substituted Thiourea Derivatives

“…The preparation of these compounds involves a novel cost-effective synthetic procedure (Ramadas & Janarthanan, 1995) and they have applications as rubber accelerators and as intermediates in dye preparation. They are also used for the synthesis of unsymmetrical thioureas (Ramadas, Srinivasan & Janarthanan, 1993), which are very useful agrochemical intermediates. We are interested in the molecular conformations and the details of the N--H...S hydrogen-bond formation of these ligands in the solid state.…”

1,3-Bis(2-chlorophenyl)thiourea

“…These thiourea complexes have applications as rubber accelerators, as intermediates in dye preparation and they are also very useful agrochemical intermediates (Ramadas, Srinivasan & Janarthanan, 1993). We are interested in the molecular conformations and the Nm H...S hydrogen-bond details of these molecules in the solid state.…”
