Stereoselective Synthesis and Reactions of 1-Seleno-4-tert-Butyl Cyclohexyllithiums
Krief, A.,Evrard, G.,Badaoui, E.,Beys, V. De,Dieden, R.
, p. 5635 - 5638 (1989)
The axial C-Se bond of seleno- and mixed selenoacetals derived from 4-tert-butyl cyclohexanones exhibit a high tendency to be cleaved by n-butyllithium.The resulting 1-seleno-4-tert-butyl cyclohexyllithiums are selectively protonated or selenylated via ax
