“…In all structures, except dinuclear 8, some CF 3 groups are rotationally disordered, as is frequently found in this type of compound. 1,[3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] Good quality crystals of Ar 2 SiCl 2 1 were obtained, but these proved to be incommensurate down to 90 K. The structure was determined successfully at 40 K (Fig. 1), and contains four crystallographically independent almost identical molecules (Fig.…”

“…These distances are appreciably shorter than the sum of the van der Waals radii, 30 and are comparable with those reported previously for group 14 derivatives of the 2,4,6-(CF 3 ) 3 C 6 H 2 , 2,6-(CF 3 ) 2 C 6 H 3 or 2,4-(CF 3 ) 2 C 6 H 3 ligands. 1,[3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19]31 Such interactions have generally been considered to enhance the stability of the compound concerned, including the dimer of 2,4,6-tris(trifluoromethyl)phenyl lithium diethyletherate. 32…”

“…Many studies have taken place in recent years using the bulky electron-withdrawing ligand 2,4,6-(CF 3 ) 3 C 6 H 2 (fluoromes) to stabilise both main group and transition metal species, including group 14 derivatives, some of which have been structurally characterised. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] Fewer reactions have been attempted with the 2,6-(CF 3 ) 2 C 6 H 3 (fluoroxyl) substituent, since lithiation of 1,3-(CF 3 ) 2 C 6 H 4 occurs in two positions, either ortho to both CF 3 groups to give the desired 2,6-(CF 3 ) 2 C 6 H 3 derivatives, or ortho to one CF 3 and meta to the second, leading to the isomeric 2,4-(CF 3 ) 2 species. Consequently mixtures of products are often obtained, which are sometimes difficult to separate.…”

Selected group 14 tetrahalides EX(4) (E = Si, Ge or Sn; X = Cl or Br) have been reacted in various molar ratios with ArLi, where Ar = 2,5-(CF(3))(2)C(6)H(3). The compounds Ar(2)SiCl(2)1, Ar(3)SiF 3, Ar(2)Si(OH)(2)4, Ar(2)GeCl(2)7, Ar(2)Ge(Br)Ge(Br)Ar(2)8, Ar(3)SnCl 10, Ar(4)Sn 11 and Ar(3)SnBr 12 have been isolated, and characterised by single-crystal X-ray diffraction, elemental analysis and (19)F solution-state NMR spectroscopy.
