Photomediated Controlled Radical Polymerization and Block Copolymerization of Vinylidene Fluoride

“…Although in the case of HVIC/R F –I mixtures, as seen above, the potential formation of CX 3 COOI (eq 3) can be neglected, rt reactions of I 2 with HVICs − ,,,, including IDAB, − ,− ,− IFAB, ,,− (ArOCH 2 COO) 2 IPh, CH 3 COOOH, − Hg­(OAc) 2 , AgOAc, − AgOPr, CF 3 COOAg, ,− (CF 3 COO) 2 Hg, etc., , as well as with R alk –I, , do proceed with the quantitative and fast formation of CX 3 COOI, even in the dark.…”

“…CX 3 COOI species are quite reactive reagents: CH 3 COOI was employed in electrophilic aromatic iodinations, − ,,,,,, iodoacetoxylations of double ,,,− , and triple bonds, and alcohol oxidations. ,, Similarly, CF 3 COOI adds to alkenes and is a stronger electrophilic iodination reagent, ,− ,, which, by contrast to CH 3 COOI, , may iodinate even the parent PhI. , Moreover, CX 3 COOI from (CX 3 COO) 2 PhI/R alk –I ,, or CH 3 COOOH/R alk –I , may oxidize R alk I to the corresponding CX 3 COOR alk . , …”

“…CX 3 COOI species are quite reactive reagents: CH 3 COOI was employed in electrophilic aromatic iodinations, [246][247][248]337,347,348,352,358,371 iodoacetoxylations of double 339,336,350,[354][355][356]360 and triple 351 bonds, and alcohol oxidations. 338,356,357 Similarly, CF 3 COOI adds to alkenes 366 a n d is a s t r o n g e r e l e c t r o p h i l i c io d i n a t io n r eagent, 322,[341][342][343][344][345]358,364 which, by contrast to CH 3 COOI, 358,365 may iodinate even the parent PhI.…”
