Regioselective Monohalogenation and Homo/Hetero Dihalogenation of Benzothioxanthene Monoimide

Through the preparation and characterization of five new derivatives, the regioselective mono and di, homo and hetero, halogenation of the benzothioxanthene (BTXI) core is demonstrated herein. All structurally solved by X‐ray crystallography, these complementary functionalized building blocks open d...

Description
Summary:Through the preparation and characterization of five new derivatives, the regioselective mono and di, homo and hetero, halogenation of the benzothioxanthene (BTXI) core is demonstrated herein. All structurally solved by X‐ray crystallography, these complementary functionalized building blocks open doors to the design of new symmetrical and asymmetrical π‐conjugated systems based on this promising but still under‐explored rylene The regioselective mono‐ and di‐, homo‐ and hetero‐halogenation of the benzothioxanthene (BTXI), an overlooked sulfur containing rylene, is reported. All structures are solved by X‐ray diffraction. These newly functionalized BTXI cores open unprecedented doors to the design of new symmetrical and asymmetrical π‐conjugated systems.
