Synthesis and characterization of some phthalanilic and maleanilic acid derivatives of arsenic(III)

Abstract

Replacement reaction of arsenic trichloride and 2-chloro- 1,3- dithia-2 -arsacyclopentane with sodium salts of phthalanilic and maleanilic acids (prepared <i>in situ </i>by the reaction of corresponding anilic acids with sodium isopropoxide in the mixture benzene and isopropanol) in the 1:3 and 1:1 molar ratios respectively, in benzene and isopropanol mixture, yield the arsenic derivatives of the type [L]₃ As and [L] AsSCH₂CH₂S (where L = phthalanilate

and maleanilate anions). These derivatives have been characterized by elemental analysis as well as IR and ¹H NMR spectral studies.
