1,4-Diphenylbuta-1,3-diene and trithiazyl trichloride 1 react to give a bi(thiadiazole) 2, an isothiazoloisothiazole 3, a dithiazolothiazine 4 and the thiazinodithiatriazepines 5 and 6, all of which could arise from initial addition of the trimer 1, or its monomer, to the conjugated diene by 1,2-,1,4- and, for the first time to an all-carbon diene, 1,3-(‘criss-cross’) cycloaddition reactions.
1,4-二苯基-1,3-二烯和三噻唑三氯化物 1 反应生成双(噻二唑)2、异噻唑异噻唑 3、二噻唑噻嗪 4 以及噻嗪二硫三氮杂卓 5 和 6、所有这些都可能是三聚体 1 或其单体通过 1,2-,1,4-环加成反应加入共轭二烯,以及首次加入全碳二烯的 1,3-("十字交叉")环加成反应。
