Question
Sequestration of oxygen by glucose oxidase improves the control over this process in its “Enz” variant. For 10 points each:
[10h] Name this process co-developed by Ezio Rizzardo, Graeme Moad, and San Thang. In this process, a thiocarbonylthio (“thio-carbonyl-thio”) reagent reacts reversibly with a radical to create an equilibrium between active and dormant states.
ANSWER: RAFT [or reversible addition-fragmentation chain-transfer; accept, but DO NOT REVEAL, RAFT polymerization or reversible addition-fragmentation chain-transfer polymerization]
[10e] RAFT is used to achieve tight control over dispersity and molecular weight distribution in these reactions, which often use free radicals as an initiator.
ANSWER: polymerization [accept radical polymerization; accept descriptions of the formation of polymers]
[10m] This radical initiator is commonly used in RAFT. This compound’s decomposition releases a molecule of nitrogen gas and two radicals containing a cyanide group.
ANSWER: AIBN [or azobisisobutyronitrile]
