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
通过自由基缩合反应合成了一系列具有各种官能团的联苯并[ b ] [1,4]噻嗪。在HOAc中,通过容易获得的2,2'-二硫代二苯胺和甲基芳基酮与AIBN作为自由基引发剂的一步反应,以中等至良好的收率(高达85%)获得联苯并[ b ] [1,4]噻嗪。联苯并[ b ] [1,4]噻嗪表现出多种形式的固态堆积。
