| Abstract: | A formic acid-catalyzed reaction of substituted cycloalkylanilines with 4,6-dibenzofuran-and 4,6-dibenzothiophenedicarboxaldehydes
in methanol-dichloromethane mixture afforded a number of the corresponding diimines, which can be of interest as components
of catalytic systems for polymerization of olefins.
Dedicated to the memory of Academician N. N. Vorozhtsov on the 100th anniversary of his birth.
