Résumé

1,1-Bis(phenylseleno)alkyllithiums are conveniently prepared from the corresponding selenoacetals and lithium tetramethylpiperidide in HMPT/THF. 1,1-Bis(methylseleno)alkyllithiums, not available by similar procedures are quantitatively obtained from 1,1,1-tris(methylseleno)alkanes and n-BuLi. These carbanions are treated with a large variety of electrophiles and the resulting products further transformed.
