芳香族三塩化アンチモン錯化物(第3報)

Abstract

In accordance with the method described in the previous paper, p-methyl-, p-ethoxy- and p-nitro- benzenediazonium tetrachloroantimonite complex were prepared by the concentrated hydrochloric acid solution of antimonytrichloride with diazotized p-toluidine, p-phenetidine and p-nitroaniline respectively and their chemical properties were studied. In water solution, the derivatives of the complex decomposed into phenol and biphenyl derivatives, but in alkaline solution, they afforded chiefly phenylstibonic acid derivatives with a small amount of phenol and biphnyl derivatives and resinous matter, in acetone solution, the main reaction was the substitution by the chlorine with an appearance of a small amount of hydrogen substituted compound, biphenyl derivatives and resinous matter, while, in the presence of Cu2Cl2, the main reaction product was stibonic acid derivatives and a small quantity of chlorine substituted and hydrogen substituted compounds were identified. Methyl and ethoxy groups favoured the stability of the complex, and the yield of stibonic acid. It was, however, remarkable in acetone solution that the formation of resinous matter was depressed by the presence of Cu2Cl2, except in the case of nitrobenzene-complex, where the yield of nitrophenylstibonic acid decreased, in spite of the fact that the nitro group favoured the arsonation by Scheller's method.
