These reactions typically involve an alkyl halide reacting with a strong base to form an alkene.
In one of these reactions, tributylphosphine and a cyanoselenium compound react with an alcohol to form a selenoxide intermediate. Performing this type of reaction on a carbinolamine yields an imine. Another example of these reactions involves using mCPBA to oxidize a tertiary amine to form an amine oxide, then heating to form the final product. One mechanism for this type of reaction minimizes steric interactions with a staggered transition state, which only forms when the reactive groups are positioned in an (*) antiperiplanar geometry. The regioselectivity of these reactions is predicted by Zaitsev's rule. These reactions typically involve an alkyl halide reacting with a strong base to form an alkene. Two substituents are removed from a molecule in this type of reaction. For 10 points, what type of reaction takes place via E1 and E2 mechanisms?
In one of these reactions, tributylphosphine and a cyanoselenium compound react with an alcohol to form a selenoxide intermediate.
