We have developed a practical stereoretentive iodine/lithium-exchange process that allows the stereodefined preparation of cis- and trans-cycloalkyllithium compounds from their corresponding stereodefined iodides. Quenching with electrophiles offers stere
cis- and trans-(4-alkylcyclohexyl)stannanes. Isomers for stereochemical studies of substitution at saturated carbon-tin bonds

The synthesis and characterization of pure cis- and trans-(4-methylcyclohexyl)- and cis- and trans-(4-tert-butylcyclohexyl)triphenylstannanes are described. Their conversion, by hydrochloric acid induced dephenylation-isopropylation, to the corresponding triisopropylstannanes proceeds smoothly to provide stereoisomers capable of providing significant information with respect to brominolysis and trifluoroacetolysis of the carbon-tin bond.
