在甲苯溶液中,在亚磷酸三乙酯存在下,采取高度稀释的方法,使4,5-二氰基-1,3-二硫杂环戊二烯-2-酮分别和多缩硫杂冠醚进行交叉偶联反应,成功地得到了不对称的2,3-二氰基四硫富瓦烯衍生物。用^1HNMR、MS、IR和EA表征了其结构,并用循环伏安法研究了它们的电化学性质,用^1HNMR初步评价了衍生物对钠离子的配合性能。
Under high dilution, the cross-coupling reactions of 4, 5-dicyano-1,3-dithiol-2-one(6) and dithia crown-ether annulated tetrathiafulvalenes(3a-3c) in toluene gave asymmetrieal dieyano tetrathiafulvalene derivatives(7a-7c) in the presence of triethyl phosphite. The compounds 7a-7c were characterized by ^1HNMR, EA, MS and YR. Their electrochemical behaviors were measured by means of cyclic voltammetry. The complexation behaviors of compounds 7a -7c for sodium ion were studied hy ^1HNMR.
