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.

This paper reports our results concerning the syntheses of various bis(alkylseleno)alkanes and some of their arylseleno analogues by different methods.The scope and limitation of each of them are presented.

Z and E 3-hydroxy-vinyl selenides can be prepared with very high stereoselectivity respectively by nucleophilic addition of selenolates to propargyl alcohols and by selenylation followed by LiAlH4 reduction of the same propargyl alcohols. 1,3-Bis(seleno)-
