AIBN-Promoted Synthesis of Bibenzo[b][1,4]thiazines by the Condensation of 2,2′-Dithiodianiline with Methyl Aryl Ketones
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.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 5460-09-3 help many people in the next few years. Quality Control of Sodium 4-Amino-5-hydroxy-2,7-naphthalenedisulfonate.
