%X A mechanistic explanation is given for the thermal rearrangement of 1,1&#8242;-dipyrazolylmethane to 4,4&#8242;-dipyrazolylmethane (dpzm). This mechanism can, in part, be used to explain the formation of 1,1,2-(4,4&#8242;,4&Prime;-tripyrazolyl) ethane (tpze) from pyrazole and trichloroethanol. An improved synthesis for dpzm and the synthesis of tpze, a new pyrazole derivative, is presented. Manuscript received 27 November 2000.
