Treatment of 6-dimethylamino-6-(2-thienyl)fulvene with lithium naphthalene followed by quenching with water gives hitherto unknown 2-cyclopentathienylidene-2H-thiapyran in one step involving a novel rearrangement, while in contrast the corresponding furyl compound leads to 4-dimethylaminoazulene.
用萘锂处理6-二甲氨基-6-(2-噻吩基)富烯,然后用水淬灭,一步制得迄今未知的2-环戊二烯基亚基-2H-噻喃,而与此相反,相应的呋喃基化合物可得到4 -二甲基氨基az。
