Abstract

The reaction of [PhCCLi]n with Se metal (1:1 equivalents) in THF/TMEDA gives the insertion product [PhCCSeLi · TMEDA · THF] 1, which is monomeric in the solid state. The reaction of PhCCPh with Li metal, generating dilithium tetraphenylbutadiene in situ, followed by the addition of elemental Se gives the selenophene [{PhC}4Se] 2, as a result of insertion of Se followed by the elimination of Li2Se. The latter provides a clean and direct route to compounds of this type.
