Hu, Zhongying,Atwood, Jerry L.,Cava, Michael P.

, p. 8071 - 8075 (1994)

The McMurry coupling reaction of thiophene-derived dialdehydes has been employed as the key step in the synthesis of the sulfur-bridged annulenes 3, 4, 6-9, and 14.Dication 9 is the second example of a peripherally aromatic (26 ?) dication of this class, while the 22 ? annulene 14 is the first neutral aromatic annulene derived from thiophene.
