Iodine monobromide is an extremely effective catalyst for the redistribution of alkoxyl groups on silicon atoms in dimethyldialkoxysilanes.The equilibrium constants of these reactions were determined at 40 deg C by means of gas chromatography.Assuming that the reaction intermediate is the dative form of a dimethyldialkoxysilaneiodine monobromide complex, a mechanism of the reaction was proposed.

The main features of model reactions of titanium and zirconium alkoxides with silazanes were studied. A method was developed for incorporating titanium and zirconium atoms into the structure of silazane polymers prepared by coammonolysis of dichlorodimethylsilane and trichloromethylsilane or by catalytic polycondensation of dimethylcyclosilazanes. These polymers were studied as ceramics precursors.

In the presence of iodine, magnesium reacts with alcohols to give magnesium alkoxides, which are treated with octamethylcyclotetrasiloxane to produce dialkoxydimethylsilanes. Similarly, magnesium reacts with 1,3, 1,4 and 1,5 diols and then with octamethylcyclotetrasiloxane, producing 2, 2- dimethyl-1 3-dioxa-2-silacyclo compounds.
Reaction of Tetraalkoxysilanes with Alkyl(aryl)chlorosilanes
Chernyshev, E. A.,Komalenkova, N. G.,Tagachenkov, A. A.,Bykovchenko, V. G.
, p. 241 - 243 (2007/10/03)
Alkyl(aryl)trichloro- or dialkyl(diaryl)dichlorosilanes react with tetraalkoxysilanes Si(OMe)4, Si(OEt)4, and Si(OBu)4 to give partially etherfied alkyl(aryl)chlorosilanes RSiCl2(OAlk), RSiCl(OAlk)2, and R2SiCl(OAlk).
