✦ Synopsis

Abstract

The ureidation reactions of 2‐ and 4‐picoline N‐oxides with 2‐chloro‐4,5‐dihydroimidazole are described. A mechanism of novel thioureidation reaction of 4‐picoline N‐oxide with 2‐(4,5‐dihydro‐1__H__‐imidazol‐2‐ylthioxy)‐4,5‐dihydro‐1__H__‐imidazole is proposed. Structural assignment is confirmed by ^1^H and ^13^C nmr as well as by X‐ray crystallography.
