5-[(tert-Butyldiphenylsilyloxy)methyl]pyridazin-3(2H)-one

Abstract

In the title compound, C21H24N2O2Si, a new pyridazin-3(2H)-one derivative, the carbonyl group of the heterocyclic ring and the O atom of the silyl ether are located on the same side of the pyridazinone ring and the C—C—O—Si torsion angle is −140.69 (17)°. In the crystal, molecules are linked by pairs of strong N—H...O hydrogen bonds into centrosymmetric dimers with graph-set notation R22(8). Weak C—H...π interactions are also observed.
