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
三(二烷基氨基)-胂(I)、-锑(II)和-铋(III)与二氧化硫反应生成相应的四烷基亚硫二酰胺和相应的金属氧化物或含有这些金属的聚合物。鉴于初始反应的牢度,这些金属酰胺的反应性遵循 III>II>I 的顺序,然而,产率以 I>II>III 的顺序降低。另一方面,三(二烷基氨基)膦以 2:1 的比例生成六烷基磷酰三酰胺和六烷基硫代磷酰三酰胺。各种磷化合物对二氧化硫的反应性随着磷原子亲核性的增加而增加;P(NEt2)3>Ph2PNEt2>Ph2POEt>PhP(OEt)2>P(OEt)3。化合物(I)、(II)的反应机理,
