The Bromination of Pyrazabole.

Abstract

The stepwise B-bromination of pyrazabole with either BBr3 or Br2 has been studied. Both 4-monobromo- and 4,8-dibromopyrazabole have been isolated and characterized. The former is a thermally unstable species, the latter is formed as a mixture of cis and trans isomers. 4,4,8-Tribromopyrazabole could not be obtained in pure state but exists in mixture with the dibromo and tetrabromo derivative. The X-ray crystal and molecular structures of pyrazabole and 4,4,8,8-tetrabromopyrazabole have been determined.
