This work is an extension of Yin's work studying the diffusion of Na ion in the PbCl2-NaCl system, but at more dilute compositions of NaCl.

Since only one example of an asymmetric synthesis which involved an intermediate containing an optically active ligand has been reported, two questions immediately arise: "Is this type of asymmetric synthesis an isolated example, or is it a stepping stone toward a generalized trend for Co (III) which may be extended to include levo rotatory, as well as dextro rotatory molecules?" In addition, asymmetric synthesis affords a new avenue for synthesizing resolved neutral complexes.

In the course of attempting to prepare 3,6-bis(hydroxy-methyl)-s-tetrazine via the reduction of 3,6-bis(carboxy)-s-tetrazine with lithium aluminum hydride, it became apparent that the tetrazine ring was cleaved.

A series of compounds were prepared by condensing 2,3-dimethyl-4,9-dioxo-1-(2-propyl)-naphth[2,3-d] imidazolium iodide with various aromatic aldehydes.

There is no available information in the literature on interaction between carboxyl hydrogen and ω-phenyl groups. Consequently, it was of interest to seek such interactions. Some form of interaction is evident from the study of the spectra of some phenylalkanoic acids and benzoyalkanoic acids.
