- Synthesis of disiloxanes containing hydroxyalkyl groups
-
Four 1,3-bis(ω-hydroxyalkyl)tetramethyldisiloxanes 2O (I; n = 3-6) were synthsized by methanolysis of the correspondig trimethylsilylterminated disiloxanes (III).The latter were obtained from 1,1,3,3-tetramethyldisiloxane (II) and the appropriate (ω-alkenyloxy)trimethylsilanes (IV).Under acidic conditions III formed in addition to I, the corresponding (ω-hydroxyalkyl)pentamethyldisiloxanes HO(CH2)nSiMe2OSiMe3 (V; n = 3-6).
