The reaction of mercury(II) trifluoroacetate with disilenes (3) and (4a,b) in tetrahydrofuran at 25 °C produces 1,2-bis(trifluoroacetoxy)disilanes (5) and (6a,b); below –15 °C, n.m.r. spectra indicate that an intermediate is formed, for which structures (7) and (8a,b) are proposed.
三氟乙酸汞(II)与二甲苯(3)和(4a,b)在四氢呋喃中于25°C反应,生成1,2-双(三氟乙酰氧基)乙硅烷(5)和(6a,b);低于–15°C,nmr光谱表明形成了中间体,为此提出了结构(7)和(8a,b)。
