Synthesis of the thiophene series 1,3-diselenanes
Direct reaction of propan-1,3-diselenol with thiophene-2-carbaldehydes in trimethylchlorosilane medium is studied. Synthetic procedure for preparation of the previously unknown 1,3-diselenanes of thiophene series is developed. Structure of the newly obtained compounds is established by 1H, 13C, and 77Se NMR spectroscopy. Chromatomass spectrometric stidy of the products obtained is carried out. In some cases reaction may be directed to the synthetis of new types of polymers of original structure. Pleiades Publishing, Inc., 2006.

A Simple Route to Sulfur Bridged Annulenes
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.
