Abstract:

The structures of three pyrazaboles have been determined by single crystal x-ray diffraction. In all three structures the pyrazabole ring adopts a pronounced boat conformation. A comparison with the nine other known pyrazabole structures, however, shows that the central B2N2 ring is quite flexible, and that is observed conformation is sensitive to substituent and packing effects.
