Abstract
Dehydrosulfurization using a hypervalent iodine(III) reagent enables a simple and efficient preparation of symmetrical and unsymmetrical carbodiimides from the corresponding thioureas. The oxidation afforded carbodiimides in excellent yields and high selectivity. A possible mechanism for the transformation is proposed.
