METHOD OF PRODUCING 1,4-DISUBSTITUTED [1.1.1.1.1] PENTIPTICENES

摘要

FIELD: chemistry.SUBSTANCE: invention relates to a method of producing 1,4-disubstituted [1.1.1.1.1] 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.1 cl, 2 ex, 3 tbl
