11 kwi 2017 · Very clever experiment where DCl is added to 1,3-pentadiene, which results in a symmetrical allylic carbocation intermediate. The deuterium label allows determination of the ratio between 1,2- and 1,4- products; as it turns out, the 1,2- products predominate.
Solution. Recognize that 1,3-pentadiene is a conjugated diene and understand that its reaction with Cl2 (chlorine) at low concentration will typically undergo an addition reaction, breaking the π-bonds in the diene and forming new single bonds to the chlorine atoms.
Piperylene or 1,3-pentadiene is an organic compound with the formula CH3−CH=CH−CH=CH2. It is a volatile, flammable hydrocarbon. It is one of the five positional isomers of pentadiene.
The question is what is the major product (s) formed from by the addition of Cl2 at a low concentration to 1,3-pentene. I know one of the major products is 1-chloro-2,4-pentene but it says there is also a product formed by the halogenation of the secondary radical.
31 lip 2021 · The Diels-Alder reaction is both a 1,4 addition or ethene to 1,3-butadiene and a 1,2 addition of butadiene to ethene. It can be called a [4 + 2] cycloaddition and as such results in the formation of a six-membered ring.
