  Abstract (C6F5)3Sb has been found to react with interhalogens and halo-pseudohalogens, IX(X = Cl, Br, N3 and NCO), pseudohalogen (SCN), and elemental sulphur to give oxidative addition products (I–VI). (C6F5)3SbS(VI) may also be prepared by the reaction of (C6F5)3SbCl2 with H2S. Metathetical reactions of (C6F5)3SbCl2 with appropriate metallic salts yield covalent pentacoordinate disubstituted products

  The title compounds have been synthesized by Grignard reactions or pyrolysis of diplumbanes respectively. The crystal structures of m-Tol4Pb and Ph4Pb (redetermination) have been determined. All eight compounds (Ph/Tol)4(Sn/Pb) are S4 symmetric and contracted along this unique axis. The 13C-NMR chemical shifts and the couplings 1J(119Sn/207Pb13C) as well depend additively upon the methyl substituents

  A general procedure for the synthesis of hexaarylated compounds of the type Ar3PbGeAr's from Ar3PbLi and Ar'3GeX in THF/ether at -60-degrees-C is given. Likewise, from Ar3PbLi and Ar'PbI the asymmetrical diplumbanes Ar3PbPbAr3 could be prepared. By the use of the bulky groups Ar and Ar', the migration of aryl groups could be suppressed, avoiding the appearance of the mixtures Pb2Ar6-nAr'n (n = 0-6). Nonetheless, the resulting diplumbanes Ar3Pb-PbAr'3 were always partially contaminated with some symmetric Pb2Ar6 and Pb2Ar'6. The structures of (p-Tol)3PbGePh3 (triclinic, space group P1BAR; a = 9.983(1) b = 12.201(1) c = 15.728(2) angstrom; alpha = 95.73(1), beta = 103.56(1), gamma = 113.06(1)degrees; V = 1674(1) angstrom3; Z = 2; R = 0.0434) and (p-Tol)3PbGe-(p-Tol)3 (trigonal, space group R3BAR; a = 13.338(1), c = 36.55(1) angstrom; V = 5631(2) angstrom3; Z = 6; R = 0.0522) have been determined. NMR chemical shifts delta(Sn-119) and delta(Pb-207) (40 compounds) and one-bond couplings 1J(M-M') (16 compounds), stretching vibrations nu(M-M') and force constants f(M-M') for a diatomic oscillator (38 compounds), and bond distances d(M-M') (18 compounds) are compared for all six combinations M/M' = Ge/Sn/Pb of Ar3M-M'Ar'3. Concerning the asymmetric diplumbanes Ar3Pb-PbAr'3, assignments of delta(Pb-207) resulted from a consideration of inductivity (comparison to PbAr4/Ar'4) and an assumed order of charge flow DELTA(Ar <-> Ar') (13 compounds). Sequences exist for delta(Sn-119) (Pb-Sn > Sn-Sn greater-than-or-equal-to Sn-Ge), delta(Pb-207) (Pb-Pb > Pb-Sn almost-equal-to Pb-Ge), f (Sn-Ge > Sn-Sn greater-than-or-equal-to Pb-Sn, and Pb-Ge > Pb-Sn greater-than-or-equal-to Pb-Pb), d (Sn-Ge less-than-or-equal-to Pb-Ge < Sn-Sn less-than-or-equal-to Pb-Sn less-than-or-equal-to Pb-Pb) and reduced spin-spin couplings 1K (Pb-Sn > Sn-Sn > Pb-Pb ''scatter''). The polarities Pb(delta-)-Ge(delta+) and Pb(delta-)-Sn(delta+) are obvious. The enhanced electronegativity of lead demonstrates the influence of its relativistically contracted 6s and 6p orbitals. With regard to Ar3Pb-PbAr'3, a relation between 1K(Pb-Pb) and the charge flow DELTA(Ar <-> Ar') is indicated.
