Following a three step route, 5,6-dihydrothieno[2,3-d]-1,3-dithiol-2-one (5) was synthesized in gram quantities starting from commercially available reagents. Coupling of 5 with trimethyl phosphite gave the Ï-donor bis(ethylenethio)tetrathiafulvalene 1 in 80% yield.
通过三步路线,我们利用市售试剂合成了 5,6-二氢噻吩并[2,3-d]-1,3-二硫环戊-2-酮 (5)。将 5 与亚磷酸三甲酯偶联,可得到Ï-载体双(乙烯硫基)四硫富戊烯 1,收率为 80%。
