Treatment with acetic anhydride of the intermediate product obtained from 3-benzoyl-6-bromochromen-2-one and [1-(4-chlorophenyl)-2-phenylethen-1-yloxy]-zinc(II) bromide resulted in the formation of 3-(1-acetoxy-1-phenylmethylidene)-6-bromo-4-[2-(4-chlorophenyl)-2-oxo-1-phenylethyl]chroman-2-one Держатели документа: Центральная научная библиотека УрО РАН Доп.точки доступа: Shchepin, V.
