6,7-DIPHENYL-2,3-DICYANONAPHTHALENE AND METHOD OF PRODUCING 6,7-DIPHENYL-2,3-DICYANONAPHTHALENE Russian patent published in 2011 - IPC C07C255/52 C07C253/30 

Abstract RU 2426725 C1

FIELD: chemistry.

SUBSTANCE: invention relates to 6,7-diphenyl-2,3-dicyanonaphthalene of formula , which can be used as starting material during synthesis of novel binuclear phthalocyanines, as well as to production method thereof. The method involves bromation of 4,5-dibromo-o-xylene with molecular bromine on light while boiling to obtain 4,5-bis(dibromomethyl)-1,2-dibromobenzene, on which sodium iodide and fumarodinitrile acts to form 6,7-dibromo-2,3-naphthalodinitrile. The latter is mixed with phenylboronic acid in the presence of tetrakis(triphenylphosphine)palladium.

EFFECT: obtaining the desired product.
