Skowronski, Romuald published the artcileBenzenic and anthracenic hydrocarbons with unsaturated side chains, HPLC of Formula: 18512-55-5, the publication is Bulletin de la Societe Chimique de France (1967), 4235-43, database is CAplus.
Benzenic and anthracenic hydrocarbons having unsaturated side chains are obtained by aromatization of the corresponding dihydroaromatic diquinols in the presence of SnCl2 in MeOH or tetrahydrofuran at ambient temperature [TABLE OMITTED] In the case of polyacetylenic diols, the acetylenic diols are reacted with a 1-bromoacetylenic compound in the presence of MeOH, EtNH2, and CuCl. Condensation of ketones with alkynylarenes in the presence of KOH in tetrahydrofuran or N-methylpyrrolidone leads to the formation of acetylenic alcs. or diols. SnCl2/AcCl reduction of the diols in tetrahydrofuran furnishes quinoid biscumulenes, while catalytic partial reduction with Pd/CaCO3 in tetrahydrofuran or chem. partial reduction with LiAlH4 in tetrahydrofuran yields cis, cis diethylenic diols and trans, trans diethylenic diols, resp. The compounds prepared are given in the table.
