Simple and efficient methodology to prepare guanidines from 1,3-disubstituted thioureas

Autor: Gil Mendes Viana, Marcio V. Costa, Lucia C. S. Aguiar, Bruno Costa, Luiz Fernando B. Malta

Publikováno v: Tetrahedron Letters. 57:1585-1588

Guanidinium salts were efficiently prepared by desulfurization reactions of 1,3-disubstituted thioureas using KICl 2 in the presence of amines. The reactions were successfully carried out at room temperature, in short reaction time, affording cyclic/
