Silicon halides amines

Silicon halides (especially the readily available chlorides) are probably the most synthetically useful and versatile monomeric inorganic silicon compounds. They may readily be reduced to hydrides, hydrolyzed to silanols (and subsequently to siloxanes), treated with other protic species such as alcohols, carboxylic acids, amines, and thiols to give SiA)R, Si-0C(0)R, Si NR2, and Si SR species respectively, used to make sUyl pseudohalogen derivatives by treatment with silver or alkali metal salts, for example, treated with sodium... 

Silastannathianes containing the unit SiSSn can be prepared from the reaction of a mixture of tin halide and silicon halide with hydrogen sulfide in the presence of an amine, and the corresponding selenium and tellurium compounds from a similar reaction using lithium selenide or lithium telluride.14... 

Simple (RO)4Si compounds may readily be prepared by the reaction between a chlorosilane and an alcohol (or phenol) (Scheme 41). A problem in this type of reaction is that the HCl formed may cause unwanted side reactions. This may be minimized by blowing dry N2 gas through the reaction mixture or heating the reaction so that HCl is driven off as it is formed, or a tertiary amine such as pyridine may be added to the reaction, which forms an amine hydrochloride salt that precipitates to remove the HCl. Silicon alkoxides may also be made by reaction of a silicon halide and an alkali metal alkoxide (Scheme 41). ...

This synthetic method is of great importance in the synthesis of silicon amides. Halides of the type R SiCL,. (x = 0, 1, 2, 3) react with ammonia or primary and secondary amines to give the corresponding amides.17"24 Again, with sterically demanding amines only partial halide displacement is possible (equations 6 and 7).22,23...
