Abstract

Various vinylsilanes, SiX(CH=CH₂)(CH₃) [2-(CH₃)₂NCH₂C₆ H₄], and ethylsilanes, SiX(CH₂CH₃) (CH₃)[2-(CH₃)₂NCH₂ C₆H₄] [X=Cl (1); OMe (2); H (3); F (4); OSiMe₃ (5); NMe₂ (6); Me (7)], were synthesized in order to investigate the electronic effect of vinyl group on silicon atom having an intramolecular coordination arm. The magnitude of Δδ (ethyl→vinyl for ²⁹Si-NMR) of chlorosilane, 1, was the biggest one among 1-7. The differences of ²⁹Si chemical shifts between vinylsilanes and ethylsilanes increased in the following order: X=Me, NMe₂<H<OSiMe₃<OMe<F<Cl.
