✦ Synopsis

The methyl&ion of sodium salts of N,R*-diarylphosphamidines by methyl iodide was studied to elucidate the effect produced by the polarity of the substituents in the smbident anion on the alkylation trend. N,N'-Diarylphosphamidines /I/" are week acids; their sodium salts /II/ are formed by the action of sodium or its hydride. When these salta are methylated by methyl iodide, the trend of reaction depends on the nature of A and B substituents /see diagram/.

N-MethyI-N-phenylnitramine was rearranged in the aqueous dioxane -sulphuric acid mixture to 2-nitro-and 4-nitro-N-methylanilines. The isomer ratio was independent of the acidity within the range of-0.3 > I4o > -2.8. Some by-products were isolated and identified e.g. N-methyl-Nnitrosoaniline, its 2-n

## Abstract Anionic polymerization of methyl methacrylate in toluene solution has been studied. The polymerizations were initiated by fluorenyllithium as well as by butyl‐, benzyl‐, and phenylmagnesium halides, and carried out in the presence of polar additives. Especially the organomagnesium initi
