DOCUMENT TYPE: Journal CA Section: 41 (Leather and Related Materials) Section cross-reference(s): 49 Ti(OBu)4 (I) [5593-70-4] reacts both with collagens and Si compds. used to waterproof leather. Leather pretreated with I reacts with AcOSiMe3 [2754-27-0], poly(hydromethylsilazane), or GKZh 94 at 120-30° without any catalyst to give films contg. chem. combined Si. The reactivity of I towards Si compds.Several reagents such as 5593-70-4 is used here. decreases in the order MeOSiMe3 [1825-61-2] > 1,1,3,3-tetramethyldisilazane [15933-59-2] > pentamethyldisiloxane [1438-82-0] > Me2PhSiH [766-77-8] ? Et3SiH [617-86-7]. Other reactive Si compds. include 3-hydroheptamethyltrisiloxane [1873-88-7]. Ti(OEt)4 [3087-36-3] is more reactive than I, e.g. Et3SiH reacts with it at 120-30° giving 11% Et3SiOEt [597-67-1] in 10 h, but there is no corresponding reaction with I. .

Process for synthesis of methoxy substituted methylsilanes: Process for synthesis of methoxy substituted methylsilanes. Legrow, Gary E. (Dow Corning Corp., USA). U.S. US 5084589 A 28 Jan 1992, 5 pp. (United States of America). CODEN: USXXAM. CLASS: ICM: C07F007-18. NCL: 556470000. APPLICATION: US 91-729955 15 Jul 1991. DOCUMENT TYPE: Patent CA Section: 29 (Organometallic and Organometalloidal Compounds) Methoxysilanes were synthesized in high yield by treating methanol with a silazane at a temp. greater than the b.p. of product methoxysilane and less than the temp. of methanol. Thus, adding 64 g of dry methanol to 133 g of tetramethyldisilazane at 50° with stirring gave 169.8 g (95%) of methoxydimethylsilane.Except for chemicals metioned above, 15933-59-2 and 67-56-1 are also used. .
