Stereochemical outcome of reactions involving 1,1-bis(seleno) 4-tert-butyl cyclohexanes

Stereoselective allylotion of conformationally rigid 4-tert-butyl-1,1,-bis(methylseleno) cyclohexanes 1 has been achieved(i) from the axial face on sequential reaction of 1 with alkyllithiums, copper iodide-dimethyl sulfide and allyl bromides and (ii) fro

77Se, 13C and 1H NMR Spectra of Phenylselenenylcycloalkanes, -cycloalkenes and Some of Their Selenoxides and 125Te NMR of a Tellurium Analogue

The 77Se, 13C and 1H NMR spectra of 46 mostly new compounds with phenylselenenyl groups attached to carbocycles and of three new corresponding selenoxides and the 125Te NMR of phenyltellurenylcyclohexane are reported.Substituent effects on the chemical sh

Stereoselective Synthesis and Reactions of 1-Seleno-4-tert-Butyl Cyclohexyllithiums

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

SYNTHESIS OF α-SELENOALKYLLITHIUM COMPOUNDS

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.

New Stereoselective Routes from Alcohols to Secondary Alkyl Bromides with Retention of Configuration

Secondary alcohols can be converted into the corresponding bromides with high stereoselective retention of configuration; this two-step process proceeds by a double inversion involving the intermediate selenides.
