Abstract

The structure of the products obtained by oxidative dimerization of tetrahydroindazolones was established as being N (1)-C (3a') dimers. In one case a C (3a)-C (3a') dimer was also isolated, but N-N'-Linked dimers were never found, contrary to a previous report in the literature. A complete 13-carbon nmr study of the monomers and their fixed methylated derivatives was performed to determine the most abundant tautomer in each case, since ...
