Abstract
255,861. Binz, A., and Rõth, C. July 22. 1925, [Convention date]. Organo arseno compounds are prepared by treating a mixture of an arsinic acid with an arsine in acid solution with reducing agents. The reaction is preferably effected at normal temperature or with cooling, and the products, which may be symmetrical or unsymmetrical and may contain substituted or unsubstituted aliphatic, aromatic or heterocyclic nuclei, are soluble in alkali. An example is given of the reduction with sodium hypophosphite and potassium iodide of a mixture of 2-oxy-5-pyridinearsinic acid and 4-axy-3-aminophenylarsine (prepared by reduction of 4-oxy-3-nitrophenylarsinic acid). Specifications 11901/11 and 255,839 are referred to. The Specification as open to inspection under Sect. 91 (3) (a) includes also examples of the reduction with sodium hypophosphite and potassium iodide of (1) 3-bromo-2-oxy-5-pyridinearsinic acid mixed with 4-oxy-3-aminophenylarsine, (2) a mixture of 2-oxy-5-pyridinearsinic acid with 4- aminophenylarsine (obtained by reduction of arsanalic acid) and (3) 3-amino-4-oxyphenylarsinic acid in conjunction with 4-oxy-3-aminophenylarsine to give 3: 3<1>-diamino-4: 4<1>-dioxyarsenobenzene. This subject-matter does not appear in the Specification as accepted.
