Article abstract of DOI:10.1016/S0022-328X(00)82810-7

1,3-Disilacyclobutanes of the types R¹R²Si<*>SiR¹R² are prepared (a) by ring synthesis from chloromethylchlorosilanes R¹R²Si(CH2Cl)Cl, (b) by thermolysis of monosilacyclobutanes , 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 methods are critically compared.
