Abstract
Reduction of the diketo selenides (I) with TiCl4/Zn-powder in refluxing THF leads to the formation of the 2,5-dihydroselenophenes (II) and the 1,3-dienes (III).
ChemInform Abstract
Reduction of the diketo selenides (I) with TiCl4/Zn-powder in refluxing THF leads to the formation of the 2,5-dihydroselenophenes (II) and the 1,3-dienes (III). At a lower temperature, (Ia) yields the selenolane derivative (IV) which is chlorinated to yield the dichloride (V). Thermally induced elimination of HCl produces 3,4-diphenylselenophene (VI).
