Substitution of fluorine in C6F5X (X  COOMe, CF3, CN, NO2) and pentafluoropyridine by the triethylgermyl group

Reactions of polyfluoroaromatic compounds with electrophilic agents in the presence of tris(dialkylamino)phosphines

“…In this case, protodefluorination was not observed. However, it was found 2 that this process can occur in the case of pentafluoropyridine and pentafluorobenzenes RCdF 5 containing electron-withdrawing substituents R. In this work, the reactions of P(NEt2) 3 with CsFsN (1), CdFsCN (2), octafluoronaphthalene Cl0Fs (3), the derivatives RCdF4CF 3 (R = F (4), 3-H (5), 4-H (6), 4-Me, or 4-(CF3)2CF), and 3-chlorotetrafluoropyridine (7) in the presence of a proton donor (H,O or MeOH) were studied with the aim of developing a general method of modification of polyfluoroaromatic compounds.…”
