Abstract
The synthesis of cis- and trans-2-(diethylaminomethyl)-cyclohexanols and their structural assignments by NMR using the shift reagent Eu(dpm)3 are described. The correlation of the induced shifts with the equation Δν = K(3 cos2θ – 1)r−3, assuming an EuO distance of 2·4 A and θ less than 30°, suggests that the interactions are pseudocontact. The values of K are 452 and 420 for the two cyclohexanols, respectively.
