ether is a very poor solvent for uranyl nitrate as compared to the alkyl ethers. Gordy and Stanford6 give spectroscopic evidence t h a t benzylamine forms abnormally strong hydrogen bonds with methyl alcohol, but weak bonds are formed by benzyl esters and beii7aldehyde with methyl alcohol. It is tempting to conclude t h a t for some reason the beniyl ratlical has the cxpectcd effect when nitrogen is the electron donor, but not when oxygen is the donor. Because of coinnion clenients of structure, i t would not be surprising if the allyl radical followed the same trend. (I,)
