= Ph, C6H4Me-o, -m, -p, or C6H4Cl-p) react with selenium dioxide suspended in benzene or in solution in ethanol to give triarylphosphine oxides, PR3O, and triarylphosphine selenides, PR3Se, or selenium, depending on the phosphine, the relative proporfions of the reagents, and the solvent. Triarylarsines do not react with SeO2 in ethanol, but reactions in benzene suspension give triarylarsine oxides
三芳基膦PR 3(R = Ph,C 6 H 4 Me- o,-m,-p或C 6 H 4 Cl- p)与悬浮在苯或乙醇溶液中的二氧化硒反应生成三芳基膦氧化物PR 3取决于磷化氢,试剂的相对比例和溶剂,可以是O和三芳基膦硒化物,PR 3 Se或硒。Triarylarsines不与SEO反应2在乙醇中,但是在苯悬浮液反应给予triarylarsine氧化物或加成化合物2AsR 3 ö·H 2的SeO 3和硒。三苯乙b啶与SeO 2反应,悬浮在苯或乙醇溶液中,得到加成化合物SbPh 3 O· SeO 2和硒。三芳基双变色氨酸与SeO 2在苯-乙醇中反应,生成十八碳三烯酸和铋(III)硒酸盐。讨论了可能的机制。
