β-ketoselenenic acids was generated at low temperature ( - 20° to - 50°) by selenoxide syn elimination of appropriate selenoxides (13-ox, 16-ox, 35-ox, 38-ox, and 39-ox). No evidence for the buildup of significant concentrations of selenenic acid was obtained. A selenolseleninate (15, 2,2' - diseleno - bis(1 - phenyl - 2 - methyl -1 - propanone) - Se - oxide) was detected as an intermediate in the decomposition
( - 20°〜 - 50°)在低温下产生的一系列的β-ketoselenenic酸通过氧化硒顺式消除适当selenoxides(13-OX,16-OX,35-OX,38-OX,和39-OX) 。没有获得明显浓度的硒酸积累的证据。甲selenolseleninate(15,2,2' - diseleno -双(1- -苯基- 2 -甲基-1 -丙酮) -硒-氧化物)被检测为在分解的中间13牛和16牛。通过NMR光谱(1 H,13 C,77 Se),并通过其热分解与亚磷酸酯(还原为二硒化物6)和二烷基胺(亚硒酰胺11形成)反应。在二苄基胺存在下分解15会导致捕获硒酸样物质(RSeSeOH),得到RSeSeN(CH 2 Ph)2(R = PhC(O)C(CH 3)2)。虽然15不能由二硒化物6的氧化来制备,这是可以制备环状selenolseleninate(4,4-二甲基-1,2- disel
