Structures of Three Pyrazaboles: 1,3,5,7-Tetramethylpyrazabole; 4,4-Bis(pyrazol-1'-yl)pyrazabole; 4,4,8,8-Tetrakis(pyrazol-1'yl)pyrazabole.

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.
