Stepwise Synthesis of Chain and Ring Siloxanes - Crystal Structures

Disilanols of the type R2Si(OH)2 (1, 2: R = CHMe2, CMe3) and the fluorosilanol (Me3C)2Si(OH)F (3) serve as starting materials in the reaction with halosilanes for the stepwise construction of chain siloxanes (4 - 15, 16 - 20).Even siloxanes with bulky tert-butyl or silylamino groups are easily prepared (10, 16, 17, 20).Crystalline silanediols (2, 14, 19) are connected in chains (19) or dimeric rings (2, 14) by hydrogen bonding.The 1,3-difluoro- (18), 1,3-dihydroxy- (19), and 1-fluoro-3-hydroxydisiloxane 6 as well as the cyclotrisiloxane 21 were isolated from the reaction of F2Si(CHMe2)2 with potassium hydroxide.Directed synthesis of Si-O six-membered rings (21 - 24) is possible via reaction of 1,3-dihydroxydisiloxanes 19, 20 with di- and trihalosilanes.The crystal structures of 2, 14, and 24 are discussed.
