Abstract

Abstract Arylated anthraquinones were prepared by Suzuki–Miyaura reactions of the bis (triflates) of various 1, 3-(dihydroxy) anthraquinones. While the reactions of the bis (triflates) of parent 1, 3-(dihydroxy) anthraquinone and of 2-chloro-1, 3-di (hydroxy) anthraquinone proceeded with very good site-selectivity, the corresponding reactions of the bis (triflate) of 2- fluoro-1, 3-diarylanthraquinones were not site-selective, which was explained based on ...
