Abstract
300,716. Albert, A. Aug. 26,1927. Arsenobenzenesare prepared by the reduction of an aromatic arsenic compound, or a mixture of two different aromatic arsenic compounds, in an acid medium using as reducing agent a mixture of hypophosphorous acid or a salt thereof with sulphurous acid or one of its salts. The proportions of hypophosphorous acid may be widely varied without affecting the nature of the product. but in the case of the sulphurous acid there should not be present more than one-third of a molecular proportion for each molecular proportion of the arsenic compound. If, however, one molecular proportion or more is used for each molecular proportion of the arsenic compound, arsenobenzenes are obtained which contain sulphur. Hydriodic acid or a salt thereof mav also be present. The products, which are crystalline, are useful therapeutically. Examples are given of the reduction of (1) the semicarbazone of 3 - aldehyde - 1 - phenoxyacetic acid-6-arsinic acid, (2) a mixture of the semicarhazones of 3-hydroxy-1-benzaldehyde-4-arsinic acid and of 3-aldehydo-1- phenoxyacetic acid-6- arsinic acid, (3) the semicarbazone of 1-benzaldehyde-3-hydroxy-4-arsinic acid, using various proportions of the reducing mixture, (4) the semicarbazone of 1-acetophenone-3-hydroxy-4-arsenoxide, (5) 3-aminobenzene-4-hydroxy-1-arsinic acid, using sufficient sulphurous acid to produce a sulphur-containing product. Specification 259,245 is referred to. The semicarbazone of 3-aldehydo-1-phenoxyacetic acid-6-arsinic acid is obtained by the action of chloracetic acid on the semicarbazone of 3- hydroxy-1-benzaldehyde-4-arsinic acid, whose preparation is described in Specification 259,245.
