Summary
-
1.
Dialkyl(or aryl)silanols containing silicon-attached hydrogen R2Si(H)OH and tetraalkyl(or aryl) disiloxanes of general formula
were synthesized and characterized for the first time, Diethylethylisobutyl-, and ethylphenyl-silanols and symmetrical tetraethyl-, diethyldiisobutyl-, and diethyldiphenyldisiloxanes were prepared.
-
2.
Chlorodiethyl-, chloroethylisobutyl-, and chloroethylphenyl-silanes were prepared for the first time.
-
3.
It was shown dialkyl(or aryl)chlorosilanes (the example taken was chlorodiethylsilane) react with ammonia with formation of disilazanes
. When hydrolyzed, 1,1,3,3-tetra ethyldisilazane gives diethylsilanol and 1,1,3,3-tetraethyldisiloxane.
-
4.
When dialkylsilanols react with vinyl ethers, organosilicon acetals of the following structure are formed:
(R1 and R2 are alkyl or aryl groups).
