Ethylation

from Wikipedia, the free encyclopedia

As ethylation a chemical reaction is referred to, one ethyl group (-C 2 H 5 ) in an organic compound is introduced. It belongs to the alkylations .

In the case of nucleophilic substitutions , ethanol , haloethanes (such as ethyl chloride or ethyl iodide ) or diethyl sulfate are often used as substrates. In addition, Grignard reactions using ethylmagnesium bromide or other organometallic reactions also allow ethylations.

An example of ethylation is the production of ethylbenzene from benzene and ethene . In the ethylation of benzene by Friedel-Crafts alkylation , the thermodynamically stable 1,3,5-triethylbenzene is formed even at low temperatures .
