An allyl group is an alkenehydrocarbon group with the formula H2C=CH-CH2-. It is made up of a vinyl group, CH2=CH-, attached to a methylene -CH2. For example allyl alcohol has the structure H2C=CH-CH2OH . Compounds containing the allyl group are often referred to as being allylic. An alkene in organic chemistry is an unsaturated hydrocarbon containing at least one carbon to carbon double bond. ... Hydrocarbons are refined at oil refineries and chemical plants In chemistry, a hydrocarbon is any chemical compound that consists only of the elements carbon (C) and hydrogen (H). ... Vinyl products (such as these records) come in many colors. ... In chemistry, methylene is a divalent functional group CH2 derived formally from methane. ... Allyl alcohol or 2-propen-1-ol is an organic compound. ...
The site of the saturated carbon atom, where the allyl group attaches (e.g. next to the OH in allyl alcohol) is called the allylic position or allylic site. A group, such as -OH, attached at an allylic site is sometimes described as allylic. Two examples of simple allyl compounds are allyl chloride and allyl alcohol. allyl chloride Allyl chloride, or 3-chloropropene, is a very toxic and highly flammable clear liquid with chemical formula CH2CHCH2Cl, insoluble in water, used as an alkylating agent. ... Allyl alcohol or 2-propen-1-ol is an organic compound. ...
Substituted versions of the above, such as the trans-but-2-en-1-yl or crotyl group (CH3CH=CH-CH2-) may be also referred to as allylic groups.
Allylic methylene groups show special reactivity such as demonstrated in allylic oxidations, ene reactions and the Trost asymmetric allylic alkylation. Selenium dioxide oxidation Allylic oxidation is an organic oxidation converting an allylic methylene group into an allylic alcohol or an ketone. ... Ene reactions are Group transfer reactions between an alkyne or alkene, or similar double bonded species and an allyl-like species. ...
Conversion of an allylic ether to its corresponding acetal
In this process an allylic ether is contacted with an organic hydroxy compound and a catalytically effective amount of a cobalt compound which results in the formation of the corresponding acetal.
A preferred class of allylic ethers, possessed of carboxylate functionality, that is reacted to form an acetal in accordance with the present invention are alkyl n-alkoxy-(n-2)-alkenoate compounds.
Wet adhesion in the latex, which is required in most paint applications, is obtained by the interpolymerization of an amine having allylic functionality directly attached to the amino nitrogen atom and at least one hydrogen atom attached directly to the amino nitrogen atom.
One of the advantages of the allylic amines, and the reason for their use in higher proportions than conventional wet adhesion monomers, is that a fraction of the amines can be cross-linked or reacted with various amine reactive compounds to provide unique properties in the polymer without significantly affecting the wet adhesion characteristics.
The polymerization of the allylic amine proceeds by conventional free radical polymerization with the exception that the allylic amines should be converted to the salt form when polymerizing in an aqueous system.
