High precision NMR study of 1,1-disubstituted silacyclobutanes
摘要:
AbstractThe hydrogen NMR spectra of 1,1‐dimethyl‐, 1,1‐dichloro‐, 1,1‐dimethoxy‐ and 1,1‐difluoro‐silacyclobutane have been analysed. A new correlation NMR instrumental technique has been used to obtain spectral parameters with very high precision.

1,3-Disilacyclobutanes of the types are prepared (a) by ring synthesis from chloromethylchlorosilanes R1R2Si(CH2Cl)Cl, (b) by thermolysis of monosilacyclobutanes R1R2H2CH2, and (c) by substitution of chlorine with alkyl groups in SiCl-containing 1,3-disilacyclobutanes, obtained by procedures (a) or (b). The compounds have been characterized by analytical and spectroscopic investigations. The synthetic
