Borane chemistry is fruitful in radical organic chemistry, and it is extending to polymer synthesis now. Triethylborane is an efficient radical initiator at ambient temperature or even below at - 78 'C, and it was successfully adopted into controlled radical polymerization at ambient atmosphere and temperature. Oxygen molecule was used to initiate the controlled radical polymerization as well as to regulate the whole process "on"/"off" with air. N-Heterocyclic carbene was further used to stabilize boryl radical, which could involve in lots of radical transformations. Herein, N-Heterocyclic carbene borane efficiently reduced and modified the chain end fidelity of polymers synthesized from RAFT and ATRP.
