Quest for diatomic selenium

Metallocene pentaselenides and elemental selenium were employed in an effort to generate diatomic selenium (Se2) under thermal conditions. Trapping experiments were carried out with six dienes. A successful formation of a diselenium adduct was observed in the case of 5,6-dimethylene-cyclohexa-1,3- diene (1a). The other dienes produced the corresponding dihydroselenophenes. The in-depth study of the limitations of our method to generate Se2 is described; a plausible mechanism rationalizing the observed results is proposed.

Synthesis and characterization of 3,4-Di-t-butylfuran, pyrrole, and selenophene

3,4-Di-t-butylfuran (1), pyrrole (2), and selenophene (4) were first synthesized using 3,4-di-t-butylthiophene (3) as the starting material and these overcrowded five-membered hetarenes including 3 were characterized by NMR and MMP2 calculations.

A NOVEL SYNTHESIS OF SELENOPHENES

Reduction of α,α'-diketo selenides with a low-valent titanium reagent usually affords 3,4-dihydroxyselenolanes, from wich the corresponding selenophenes are obtained by acid-catalyzed dehydration.A surprising exception is the formation of 2,4-dihydroy-2,4-di-t-butylselenolane from bis(2-t-butyl-2-oxoethyl) selenide, the former being converted to 2,4-di-t-butylselenophene by acid treatment.
