Draw curved arrow mechanisms for the rin cationic initiator and (b) an anionic initiator You should Then, comment on which method you expect to produce a s for the ring-opening polymerization of E-caprolactone using (a) a monic initiator Vou should show an initiation and a propagation step. od you expect to produce a narrower molar mass distribution and why. -NH E-caprolactone
Mechanisms Question 1 (22 marks) (a) Consider the radical chain reactions of the alkane shown below with Br, in the presence of light. H3C HH H C-CCHS CH3 Br2 hv 2 Different mono- bromo products 25 °C + (you will need to look up the bond dissociation energy (BDE) for the types of bonds formed and broken in this reactions) (i) Give the structures of the products from the reaction and using standard arrow conventions show the series of mechanistic...
b. As was shown for cationic polymerization reactions, a depolymerization reaction referred to as "back-biting" can also occur during ROMP. Propose a mechanism for this depolymerization reaction using your structure from part a. You may use an abbreviated structure to simplify the drawing.
