Starting from 1,1-dichloro-2-methyl-1-silacyclobutane (I) we have synthesized the silacyclobutanes II–V, containing phenyl or t-butyl ligands bonded to silicon. The silacyclobutanes VIII and IX with phenyl ligands at the α-C-atom were prepared from the (3-bromo-3-phenylpropyl)halosilanes VI and VII by intramolecular Grignard reactions. From VIII we obtained the silacyclobutanes X and XI with t-butyl
