Reactions of SiF2 with halogens have been reinvestigated by both co-condensation and gas-phase methods. The co-condensation method yields a number of fluorohalogenosilanes including mono-, di-, and higher silane derivatives. These compounds contain SiF, SiF2, and SiF3 units. The reactivity towards SiF2 decreases from chlorine through bromine to iodine. While chlorine and bromine give rise to a number
SiF 2与卤素的反应已通过共缩合和气相方法进行了重新研究。该共缩合方法产生许多氟代卤代硅烷,包括单,二和高级硅烷衍生物。这些化合物包含SiF,SiF 2和SiF 3单元。对SiF 2的反应性从氯到溴再到碘。尽管氯和溴会生成许多氟代卤代硅烷,但碘只能生成甲硅烷衍生物。相反,气相反应没有进行到任何明显的程度。产品已通过质谱和19 F和29进行了表征Si nmr光谱。许多是第一次被发现。
