RAFT polymerisation of trifluoroethylene: the importance of understanding reverse additions

“…10,14,37,38 The HH reverse additions proved to play a crucial role in the RAFT polymerisation of VDF as they were shown to be responsible for the slowdown of the RAFT equilibrium and ultimately for the loss of control. 23,30 The chain ends formed during the RAFT polymerisation of TrFE and their evolution with conversion were thus examined.…”

“…16 Reversible Deactivation Radical Polymerisation techniques, have not yet been employed to polymerise TrFE. 17 Several articles report the telomerisation of TrFE using various transfer agents such as hydrogen disulfide 18 ,mercaptan and trifluoromethanethiol, 19 bistrifluoromethyl disulphide, 20 iodine monochloride, 21 or dibromodifluoromethane 22,23 for example. Balagué et al studied the telomerisation of TrFE using fluoroalkyl iodides as transfer agents.…”

Visible Light‐Mediated Metal‐Free Chlorodifluoromethylation of Arenes and Heteroarenes by a Hypervalent Iodine EDA Complex

“…[24] While there have been many radical difluoromethylation methods reported in recent years, radical chlorodifluoromethylation procedures remain scarce and underexplored. Current methods require strong oxidants [28] (Scheme 1a, b, c, d) and freons [29,30] (Scheme 1c, Scheme 1d), require multistep reagent synthesis [24] (Scheme 1b), or use exogenous photocatalysts [23,31] (Scheme 1e, Scheme 1f).…”
