<i>O,S</i>-Acetals in a New Modification of <i>oxo</i>-Friedel–Crafts–Bradsher Cyclization—Synthesis of Fluorescent (Hetero)acenes and Mechanistic Considerations

This paper presents the use of <i>O,S</i>-acetals in a new modification of the <i>oxo</i>-Friedel–Crafts–Bradsher cyclization. In this reaction, under mild reaction conditions (25 °C), three- and four-ring fused <i>RO</i>-acenes (major) and/or <i>HO(CH<su...
