A simple procedure for a high yield preparation of CF2(SF3)2 (1) from CS2 and elemental fluorine is described. In the presence of CsF 1 is further oxidised by F2 and C1F to give F2C(SF5)2 (4) and (trans - C1SF4)2CF2 (5), respectively.
描述了一种由CS 2和元素
氟高产率制备CF 2(SF 3)2(1)的简单程序。在CsF 1存在下,进一步被F 2和ClF氧化,分别得到F 2 C(SF 5)2(4)和(反式-C1SF 4)2 CF 2(5)。
