elimination to yield compounds of the type TsiSiFR,R′ (R, R′ = alkyl, aryl). The hydrolyzability and the products of hydrolysis of the fluorosilyl-substituted tris(silyl)methanes vary considerably. TsiSiFR2 compounds are resistant to hydrolysis. The compounds TsiSiF3 (I) and TsiSiF2Me (II) condense when hydrolyzed. The initial fluorosilanol, TsiSiF(OH)Me, can be isolated. The compounds TsiSiF2R (R = CHMe2
三(三甲基甲硅烷基)甲烷锂(TsiLi)通过消除LiF与氟代硅烷反应,生成TsiSiFR,R'类型的化合物(R,R'=烷基,芳基)。氟甲硅烷基取代的三(甲硅烷基)甲烷的水解性和水解产物变化很大。TsiSiFR 2化合物具有抗水解性。水解时,化合物TsiSiF 3(I)和TsiSiF 2 Me(II)缩合。可以分离出初始的氟硅烷醇TsiSiF(OH)Me。化合物TsiSiF 2 R(R = CHMe 2(III),C 6 H 5(IV),CMe 3(V))通过甲硅烷基的1,3-迁移进行水解,得到相应的1,3-二硅氧烷(Me 3 Si)2 CHSi(F)ROSiMe 3(R = CHMe 2(XII),C 6 H 5(XIII),CMe 3(XIV))。通过金属化并与Me 3反应,SiCl XIII可以转化为三(甲硅烷基)甲基化合物TsiSi(F)C 6 H 5 OSiMe 3(XV)。XV也可以从IV和LiOSiMe
