Cyanic Acid Esters. 29. Benzoxazoline-thione-N-imid Esters and Their Consecutive ReactionsOxazoline-thiones-(2) and aryl cyanates react to form the corresponding isoureas 4. These compounds are remarkably stable against electrophilic reagents. The aminolysis of 4 proceeds two pathways: a transformation of the imid ester residue to the amin and a ring opening reaction by attack of the amin to the C=S-bond. The hydrazinolysis causes a ring-transformation of the oxazoline- to the 1,3,4-triazole system.
