The previous route was reduction of the peroxide brige to yield 3α,6α-dihydroxy cyclohexene, followed by di-hydoxylation of the double bond; which yielded a mixture of the 1,4/2,3 and 1,2,3,4/0 isomers. The authors found that, by reversing the order of the two steps, they could obtain 1,4/2,3 in 80% yield. [9] [10] [11]
Functional isomers are structural isomers which have different functional groups, resulting in significantly different chemical and physical properties. [ 11 ] An example is the pair propanal H 3 C–CH 2 –C(=O)-H and acetone H 3 C–C(=O)–CH 3 : the first has a –C(=O)H functional group, which makes it an aldehyde , whereas the second has ...
In chemistry, isomerization or isomerisation is the process in which a molecule, polyatomic ion or molecular fragment is transformed into an isomer with a different chemical structure. [1] Enolization is an example of isomerization, as is tautomerization. [2] When the isomerization occurs intramolecularly it may be called a rearrangement reaction.
The molecular formula C 3 H 6 O may refer to: . Chemistry portal; Alcohols. Allyl alcohol or 2-propen-1-ol, CH 2 =CH-CH 2 OH, CAS number 107-18-6; cyclopropanol or cyclopropyl alcohol, cyclo (-CH 2-CH 2-HOHC-), CAS number 16545-68-9
Cycloisomerization is a very broad topic in organic synthesis and many reactions that would be categorized as such exist. Two basic classes of these reactions are intramolecular Michael addition and Intramolecular Diels–Alder reactions. Under the umbrella of cycloisomerization, enyne and related olefin cycloisomerizations are the most widely ...

In organic chemistry, functionality is often used as a synonym for functional group. For example, a hydroxyl group can also be called a HO-function. [1] [2] Functionalisation means the introduction of functional groups, for example the functionalisation of a surface [3] (e.g. silanization for the specific modification of the adhesion of a surface)
