A mechanism involving hydrogen bonding with fluorine attached to carbon was proposed to explain acid catalyzed reactions of alkyl fluorides.The reaction of the benzyl fluorides with sodium iodide in acetone was found to be extremely slow.Ithaca, X. Y.

Unsubstituted DL-glutamic acid has been resolved by use of an optical isomer of the readily available l-hydroxy-2-aminobutane. The amine used was obtained by resolution with either tartaric acid or glutamic acid. Attempts to extend this method to aspartic acid resulted in partial resolution only. Formyl-DL-phenylalanine, however, was resolved to give the pure isomers readily. Mutual solubilizing effects are described for diastereomers of the hydroxybutaneammonium hydrogen glutamate.
