and DTA of (CH 3 ) 2 Sn(SO 3 F) 2 , (CH 3 ) 2 Sn(SO 3 CF 3 ) 2 , and (CH 3 ) 2 SnF 2 were carried out under a dynamic nitrogen atmosphere. The decomposition of (CH 3 ) 2 Sn(SO 3 F) 2 proceeds via (CH 3 ) 2 SnF(SO 3 F) ultimately giving SnO 2 . (CH 3 ) 2 SnF 2 , however, decomposes concurrently with sublimation near 360 °C, whereas (CH 3 ) 2 Sn(SO 3 CF 3 ) 2 first loses C 2 F 4 , forming the transient
摘要 (CH 3 ) 2 Sn(SO 3 F) 2 、(CH 3 ) 2 Sn(SO 3 CF 3 ) 2 和(CH 3 ) 2 SnF 2 的TG和DTA在动态氮气氛下进行。(CH 3 ) 2 Sn(SO 3 F) 2 的分解经由(CH 3 ) 2 SnF(SO 3 F) 进行,最终得到SnO 2 。然而,(CH 3 ) 2 SnF 2 会在 360 °C 附近与升华同时分解,而 (CH 3 ) 2 Sn(SO 3 CF 3 ) 2 首先失去 C 2 F 4 ,形成瞬态物质 (CH 3 ) 2 Sn (SO 3 CF 3 )(SO 3 F) 在 120 到 310°C 之间,此后产品似乎在 310-450°C 范围内升华。
