α-Phenylselenoalkyllithiums and α-methylselenoalkyllithiums have been prepared from the corresponding selenoacetals and alkyllithiums.Several features of this reaction are disclosed.For example, the reaction is more readily achieved on phenylselenoacetals than on methylseleno analogues.Those derived from hindered carbonyl compounds are less readily cleaved. s-BuLi/THF proved superior to n-BuLi in THF, itself better than n-BuLi in ether.
A NOVEL METHOD FOR THE GEMINAL DIALKYLATION OF THE CARBONYL GROUP OF AROMATIC ALDEHYDES AND KETONES

The title transformation is efficiently achieved by using the selenium methodology which involves the sequential reductive alkylation of arylselenoacetals and of benzylselenides.
METALLATION OF BENZYL SELENIDES AND OF α-ARYL SELENOACETALS. SCOPE AND LIMITATIONS.
Clarembeau, M.,Krief, A.
, p. 1723 - 1726 (2007/10/02)
α-Metallo benzylselenides and α-metallo selenoacetals derived from aromatic aldehydes have been conveniently prepared by metallation of the corresponding carbon acids.KDA in THF proved among the various basic systems tested, the most efficient.
NOVEL SYNTHESIS OF BENZYLLITHIUMS FROM BENZYLSELENIDES
Clarembeau, M.,Krief, A.
, p. 1093 - 1096 (2007/10/02)
Benzylselenides are found to be valuable precursors of benzyllithiums.The scope of the new method is disclosed.
