Action of Alcohol on Diazo-Compounds. Ira Itemsen. Ber. IS, \V. HOFMANN, Hallen, and of Wroblewsky (Ber. 17,1017, 1SS7, and 2703), and other investigators, have foundthat a diazo-compound, when decomposed by boilingwith alcohol, does not always yield the correspondinghydro-carbon as previously supposed, but that sunn him vthe ethyl-ether of the corresponding phenol is produce, author points out that Brown (Amer. Chem. , 374) has also made the same observation, obtainingcthoxymetatoluic acid by boiling the diazo-compound of. in a cold dilute, acid solution—bye-products of a red amidometatoluic acid with alcohol. Palmer has just colour, and containing a larger amount of sulphur, are found that by the decomposition of the diazo derivative of formed, and that the greater pxrt of the sulphuretted amido-orthotolnene sulphonic acid by alcohol, both hydrogen is oxidised to water and sulphur without orthotoluene sulphonic and ethoxyorthotoluene sul- taking part in the reaction.
