The mono- and bisphenylhydrazones of 3-R-1,5-diphenylpentane-1,5-diones were obtained, and their transformations in the Fischer indole synthesis under various conditions were studied. It was shown that 4-R-2,6-diphenylpyridines, 2-phenylindole, and 5-R-1,-3-diphenyl-Δ2-pyrazolines are formed as the main products in addition to the 3-R-1-phenyl-3-(2-phenyl-3-indolyl)propan-1-ones or their phenylhydrazones produced as a result of indolization. The ways of formation of these compounds are discussed. Some transformations of the obtained ketones were studied.
