Magnetic birefringence effect in solutions of paramagnetic substances. 5. Structure of adducts of certain α-epoxides and keto derivatives with Dy(III) dipivaloylmethanate

Adduct formation of Dy(DPM)3 and Eu(DPM)3 with propylene oxide, 3-carene trans- and cis-oxides, cyclohexanone, d- and l-camphor, l-α-bromocamphor, and DMF has been studied using paramagnetic birefringence and polarimetry. The orientation of the chelate rings in Ln(DPM)3 and the composition and structure of the adducts formed were determined.
