✦ Synopsis

The 13 C cross-polarization magic angle spinning NMR spectra of N-( ) indicate a keto-hydroxy tautomerism of 1 but not of 2. This was confirmed by a single-crystal x-ray diffraction study of 1, which revealed that the two distinct molecules in the unit cell are linked by intermolecular hydrogen bonding. The presence of this bonding may explain the occurrence of the keto-hydroxy tautomerism.

The hydrogen bond is the most important of all directional intermolecular interactions. It is operative in determining molecular conformation, molecular aggregation, and the function of a vast number of chemical systems ranging from inorganic to biological. Research into hydrogen bonds experienced a
