Tetrahedron: Asymmetry | Cas: 2235-01-0 was involved in experiment

The unique properties of ethers (i.e., that they are strongly polar, with nonbonding electron pairs but no hydroxyl group) enhance the formation and use of many reagents. For example, Grignard reagents cannot form unless an ether is present to share its lone pair of electrons with the magnesium atom.Computed Properties of C15H16O2

Braslau, Rebecca;Burrill, Leland C. II;Chaplinski, Vladimir;Howden, Rodney;Papa, Patrick W. published 《Studies in the stereoselective trapping of prochiral carbon radicals by optically active camphoxyl nitroxides》 in 1997. The article was appeared in 《Tetrahedron: Asymmetry》. They have made some progress in their research.Computed Properties of C15H16O2 The article mentions the following:

Optically active camphoxyl nitroxides, e.g. I, derived from camphene react with prochiral carbon radicals to give diastereomeric coupling products, e.g. II. The diastereomeric ratio can be conveniently measured by 1H-NMR spectroscopy, in contrast to previous work employing steroidal nitroxides. The structure of the camphoxyl radical was modified and all couplings resulted in modest diastereoselectivity.Dimethoxydiphenylmethane (cas: 2235-01-0) were involved in the experimental procedure.
