Abstract
Upon reaction of 1,3,5-triphenyl- and 1,3,5-triphenyl-5-methyl-2-pyrazolines with antimony pentachloride in acetonitrile they undergo oxidation to cation radicals, which subsequently undergo rapid dimerization at the para positions of the N-phenyl groups. The final products are 4,4′-bis(3,5-diphenyl-2-pyrazolin-1-ia)- and 4,4′-bis(3,5-diphenyl-5-methyl-2-pyrazolin-1-ia)bis(cyclohexa-2,5-dienylidene) hexachloroantimonates.
