FIELD: chemistry.
SUBSTANCE: invention relates to a method of producing 1,4-disubstituted [1.1.1b.1.1] pentipticenes 
, R = C=C-Ar; thienyl-2. The method involves reaction of pentipticene quinone with lithium derivatives of hetarenes and acetylenes, followed by aromatisation with a reducing agent. The method is characterised by that the reducing agent used is zinc dust in acetic acid.
EFFECT: use of the present method enables to increase output of the end product; the method is also simple and environmentally friendly and does not require use of expensive catalysts.
