AIBN-Promoted Synthesis of Bibenzo[ b][1,4]thiazines by the Condensation of 2,2'-Dithiodianiline with Methyl Aryl Ketones. | LitMetric
A series of bibenzo[ b][1,4]thiazines with various functional groups has been synthesized by a free-radical condensation reaction. Bibenzo[ b][1,4]thiazines were obtained in moderate to good yield (up to 85%) through a one-step reaction of readily available 2,2'-dithiodianiline and methyl aryl ketones with AIBN as radical initiator in HOAc. Bibenzo[ b][1,4]thiazines exhibit diversiform solid-state packing.
