<i>N</i>-Silylated benzoxazolin-2-one reacts with N−H and C−H acidic heterocycles (benzoxazolinone, 3,5-dimethylpyrazole, <i>N</i>-methylimidazole) under benzoxazolinone ring cleavage and formation of <i>ortho</i>-siloxyphenyl-substituted ureas and carbamides, respectively. These products were shown to serve as sources for tridentate (O′NO) and (N′NO) chelating ligands.
