to form six linear annelated pentacyclic heterocycles with a sulfur-containing central ring (1,4-dithiin, 1,4-thiazine, 1,4-thiaselenin, 1,4-oxathiin and thiopyran) in moderate to good yields. The X-ray study of selected heteropentacenes revealed that heteropentacenes, in contrast to homopentacene, are non-planar and folded along the central sulfur-heteroatom axis. The central six-membered ring is
2,2'-二氯-3,3'-二喹啉基硫与选定的S-,O-,Se-,C-和N-亲核试剂的反应以杂环封闭方式进行,从而形成六个带有硫的线性退火五环杂环含中心环(1,4-二硫精, 1,4-噻嗪, 1,4-硫代木素, 1,4-草胺素 和 硫吡喃)以中等到良好的产量。选定的杂戊烯的X射线研究表明,与高并五苯相反,杂戊烯是非平面的,并沿中心硫-杂原子轴折叠。中央的六元环呈船形。
