Reactions of Polyfluoroarenes with MenE-MMe3 Reagents (MenE = Me2As, Me2P, Me2N, and MeS; M = Si, Sn): Synthesis of Polyfluoroaryl MenE CompoundsDedicated to Professor Dieter Naumann on the Occasion of his 60th Birthday

Abstract

Trimethylsilyldimethylarsane Me 3 SiAsMe 2 was used as a reagent for the substitution of fluorine in polyfluoroarenes C 6

Octafluoro-4,4′-bipyridine and its derivatives: Synthesis, molecular and crystal structure

“…All the other angles are usual for bipyridines. The similar angles distribution was previously observed in the halogenated 2-aminopyridines [20,21].…”

Synthesis of 2,6- and 2,3-Difluorophenyldimethyl(thio)phosphines

“…This interaction, analogous to the effect of the built-in solvation [6] was observed for a number of groups, including those like P(S)Me 2 [2], P(S)Ph 2 , and P(O)Ph 2 [7]. The ability of fluorine to take part in coordination of this type was formerly assumed for understanding the kinetics of alkoxy-and piperidinodefluorination of the hexafluorobenzene and its derivatives [8].…”

“…and pentafluoropyridine by PMe 2 groups effected by Me 3 SiPMe 2 is a convenient and efficient method of synthesis of polyfluoro-aryldimethylphosphines [1,2]. These phosphines like their less fluorinated analogs are of interest as potential ligands of catalytically active complexes of transition metals and as initial substances for preparation of biologically active phosphorus-containing heterocyclic and other compounds [3].…”

Reactions of HMPA with hexafluorobenzene, pentafluorochlorobenzene and pentafluorophenol

“…The use of HMPA to effect N,Ndimethylamination of aromatic substrates has captured wide interest previously, for example, the reaction of HMPA with halogenated aromatics containing electron-withdrawing groups [9][10][11]. The synthetic usefulness of the N,N-dimethylamination of fluoroaromatics has been well documented [3,[12][13][14][15][16]. However, to the best of our knowledge, the reaction between HMPA and hexafluorobenzene or its derivatives has never been reported.…”
