Chapter 28, Problem 60P

Although chain branching in radical polymerizations can occur by intermolecular Habstraction as shown in Mechanism 30.2, chain branching can also occur by intramolecularH abstraction to form branched polyethylene that contains butyl groups asbranches.

Chapter 28, Problem 60P, 30.59 Although chain branching in radical polymerizations can occur by intermolecular H abstraction

a. Draw a stepwise mechanism that illustrates which H must be intramolecularly abstracted to form butyl substituents.

b. Suggest a reason why the abstraction of this H is more facile than the abstraction of other H’s.

It is not unexpected that the methoxyl substituent on a cyclohexane ring prefers to adopt the equatorial conformation. OMe H A G₂ = +0.6 kcal/mol OMe What is unexpected is that the closely related 2-methoxytetrahydropyran prefers the axial conformation: H H OMe OMe A Gp=-0.6 kcal/mol Methoxy: CH3O group Please be specific and clearly write the reason why this is observed. This effect that provides stabilization of the axial OCH 3 group in this molecule is called the anomeric effect. [Recall in the way of example, the staggered conformer of ethane is more stable than eclipsed owing to bonding MO interacting with anti-bonding MO...]
