Reduction of a,a'-diketo selenides with a low-valent titanium reagent usually affords 3,4\_dihydroxyselenolanes, from which the corresponding selenophenes are obtained by acid-catalyzed dehydration. A surprising exception is the formation of 2,4-dihydroxy-2,4-di-t\_butylselenolane from bis(2-t-butyl
