Reduction of α,α′-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--butylselenolane from bis(2--butyl-2-oxoethyl) selenide, the former being converted to 2,4-di--butylselenophene by acid treatment.
用低价钛试剂还原α,α′-二硒代硒化物通常得到3,4-二羟基硒代戊烯,通过酸催化的脱水从中获得相应的硒代苯。一个令人惊讶的例外是由双(2--丁基-2-氧代乙基)硒化物形成2,4-二羟基-2,4-二-丁基硒醇,前者被酸转化为2,4-二-丁基硒吩。治疗。
