Abstract in English:
Reactions of di-silver-1,n-alkanedisulfonates, Ag2[O3S(CH2)nSO3] (n = 1, 2), with Cl2SiR1R2 (R1 = R2 = Me, Ph; R1 = Me, R2 = Ph) lead to the monomeric 3,3-diorgano-2,4-dioxa-1,5-dithia-1,1,5,5-tetraoxide 3-silacyclohexanes I (n = 1) and -heptanes I (n = 2). In the case of I (n = 1), a competition reaction is obsd. leading to the dimerization products II. The six-membered ring-systems of I (n = 1) are compared with related silanes. An x-ray structure anal. is performed for 3,3-diphenyl-2,4-dioxa-1,5-dithia-1,1,5,5-tetraoxide 3-silacycloheptane I (n = 2, R1 = R2 = Ph).
