N,N'-LINKED BIAZOLES. PART 5. SYNTHESIS OF PYRAZOLYL DIMERS BY THE REACTION OF 3-METHOXYCARBONYL-2-PYRAZOLINE WITH LEAD TETRAACETATE

Contrary to a previous report by Akhrem et. al. (Tetrahedron Lett. 1973, 2655), the reaction of 3-methoxycarbonyl-2-pyrazoline with lead tetraacetate affords not only 3-methoxycarbonyl-1-(3-methoxycarbonyl-2-pyrazolin-1-yl)pyrazole (8) and 3-methoxycarbonyl-1-(1-methoxycarbonyl-1-cyclopropyl)pyrazole (9), but a complex mixture of pyrazoles and pyrazolines depending on the reaction conditions (LTA/pyrazoline ratio and temperature).The structures of all compounds have been established, and a new mechanism is proposed for the reaction.The oxidation of 8 with N-bromosuccinimide gave the symmetrical 3,3'-dimethoxycarbonyl-1,1'-bipyrazole (17).
