History of elementoorganic compounds

Silicone chemistry also develops by leaps and bounds. The first silicon-and carbon-containing compound, ethyl ether of orthosilicon acid, was obtained by the French scientist Ebelmen in 1844. Subsequently, in 1963, Friedel and Crafts synthesized the first silicone compound with a Si-C bond, tetraethylsilane. At the initial stages of silicone chemistry, the researchers attention was attracted to silicon, the closest counterpart of carbon. It seemed that silicon could give rise to as large a subdiscipline as chemistry itself. Yet, it was found that silicon, unlike carbon, does not form stable molecular chains from successively bonded Si atoms, and the interest for organic silicone derivatives dropped. 

As stated above, polyorganosiloxanes were the first representatives of high-molecular compounds with inorganic main molecular chains sur- 

Researchers of polymer synthesis focus their attention on 45 elements of the periodic table. The most important elements used to construct 

Elementorganic compounds considerably differ in their properties and structure from both organic and inorganic compounds, occupying an intermediate position. Elementorganic compounds are rarely found in nature and are obtained synthetically. 

We can single out several fundamental characteristics which distinguish elementorganic compounds from carbon compounds.
