• Tris(dialkylamino)-arsines (I), -stibines (II), and -bismuthines (III) react with sulfur dioxide to give the corresponding tetraalkylsulfurous diamides and the corresponding metal oxides or polymers containing the metals. The reactivity of these metal amides in view of the fastness of the initial reactions follows the order III>II>I, however, the yields decrease in the order I>II>III. Tris(dialkylamino)phosphines, on the other hand, give hexaalkylphosphoric triamides and hexaalkylphosphorothioic triamides in a ratio of 2 : 1. The reactivity of the various phosphorus compounds toward sulfur dioxide increases with increasing nucleophilicity of the phosphorus atom; P(NEt<SUB>2</SUB>)<SUB>3</SUB>>Ph<SUB>2</SUB>PNEt<SUB>2</SUB>>Ph<SUB>2</SUB>POEt>PhP(OEt)<SUB>2</SUB>>P(OEt)<SUB>3</SUB>. The reaction mechanism of compounds (I), (II), and (III) with sulfur dioxide is different from that of the phosphorus amides.
