Chapter 6: Reactions of Alkenes : Addition Reactions | |
Summary
Alkenes contain the unsaturated C=C functional group
which characteristically undergo addition reactions.
In general trems, this is driven by the conversion of the weaker π
bond into 2 new, stronger σ bonds.
The reactions of alkenes can seem a little bewildering as a wide variety of
reagents undergo this type of reaction providing access to products with various
regioselectivities and stereoselectivities depending on the reagent and / or
reaction conditions, but ultimately on the mechanism by which the reaction occurs.
There are potentially 3 factors associated with each of the addition reactions of alkenes:
| Study Tip: For each reagent, identify the electrophilic atom as it will be involved in the first step of adding to the π bond and it will add to the less highly substituted position so controlling the regioselectivity of the reaction. |
