摘要:The Reaction Of Diethyl [2-(Triethoxysilyl)Ethyl]Phosphonate With Boron Trifluoride Etherate Was Used To Synthesize Diethyl [2-(Trifluorosilyl)Ethyl]Phosphonate. The Reaction Of Bis(Trimethylsilyl) Styrylphosphonate With Chloro(Chloromethyl)Dimethylsilane Gave Bis [(Chloromethyl)Dimethylsilyl] Styrylphosphonate. Multinuclear H-1,C-13,F-19,Si-29,And P-31 N Mr Spectroscopy Established The Absence Of A O-> Si Coordination Bond In These Compounds And The Four-Coordinate State Of The Silicon Atom. Evidence For This Finding Was Obtained By B3Lyp/6-31G(D) Quantum-Chemical Calculations. However,The Same Calculations For R2P(=o)Center Dot Ch2Ch2Sif3 (R = Me,Me2N) Showed The Presence In Such Molecules Of An O-> Si Coordination Bond Both In The Gas Phase And In Cho Solution. The Distance Between The O And Si Atoms In This Series Molecules Decreases With R In The Order: Meo > Me > Men. The Axial Si-F Bond Length Increases In The Same Order And Parallels The Order Of The Hammet Sigma(0)(M) Constants Of These Substituents,Relating To Their Interaction With Pi-Electron Systems.
