Abstract

A mechanistic explanation is given for the thermal rearrangement of 1,1′-dipyrazolylmethane to 4,4′-dipyrazolylmethane (dpzm). This mechanism can, in part, be used to explain the formation of 1,1,2-(4,4′,4″-tripyrazolyl) ethane (tpze) from pyrazole and trichloroethanol. An improved synthesis for dpzm and the synthesis of tpze, a new pyrazole derivative, is presented.
