The reactions of trimethyltin hydride and dimethyltin dihydride with (CH3)3SiCF=CF2 and (CH3)2Si(CF=CF2)2 respectively have been investigated. Under thermal conditions, reaction led to organotin fluorides and fluorovinyl-silanes. However, under ultraviolet irradiation at 25°, addition products were isolated of which (CH3)3SiCFHCF2Sn(CH3)3 and (CH3)3SiCF[Sn(CH3)3]CF2H were fully characterized. Evidence is presented which shows that these addition products are formed by a free radical process and that their decomposition to organotin fluorides and fluorovinyl-silanes proceeds via a β-fluorine elimination. Spectroscopic data are presented for a number of new organo-silanes.
三甲基锡氢化物和二甲基锡二氢化物分别与(CH3)3SiCF=CF2和(CH3)2Si(CF=CF2)2反应已经被研究。在热条件下,反应导致有机锡氟化物和氟乙烯基硅烷。然而,在25°的紫外辐射下,分离出加成产物,其中(CH3)3SiCFHCF2Sn(CH3)3和(CH3)3SiCF[Sn(CH3)3]CF2H已经完全表征。提供了证据表明这些加成产物是通过自由基过程形成的,并且它们分解为有机锡氟化物和氟乙烯基硅烷是通过β-氟消除进行的。为一些新的有机硅烷提供了光谱数据。
