Aromatic Hydrocarbons. LXVIII. Triangulene Derivatives. Part III

10.1021/ja01642a044

The study primarily focuses on the synthesis and analysis of various aromatic hydrocarbons and their derivatives. Key chemicals involved include heptaphene, maleic anhydride, dibenzoylphenanthrene, 2,3,8,9-dibenzopicene, and their respective derivatives. Heptaphene was synthesized and characterized by its melting point and solubility properties. Maleic anhydride was used to form an adduct with heptaphene, resulting in the dianhydride (IV). Dibenzoylphenanthrene and 2,3,8,9-dibenzopicene were synthesized through specific reaction sequences involving aluminum chloride and other reagents, and their properties were analyzed. The study also involved the synthesis of 2,3,8,9-dibenzopicene-l,4,7,10-diquinone and its derivatives, exploring their chemical behaviors and properties. The research aims to understand the structural and chemical characteristics of these compounds, contributing to the broader knowledge of aromatic hydrocarbons and their potential applications.
