Peter Lange, Annette Schier, Jürgen Riede, Hubert Schmidbaur* Anorganisch-chemisches Institut der Technischen Universität München, Lichtenbergstraße 4, D-85747 Garching Z. Naturforsch. 49b, 642-646 (1994); received January 21, 1994 Gold(I) Complexes, Gold(I) Nitrogen Bond, Diacylamido Complexes, Phthalimide [0(A uPPh3)3]+BF4_ has been found to be a powerful aurating reagent for phthalimide, to give (phthalimido)(triphenylphosphine)gold(I) (1) in high yield. Two different crystal sys tems, with or without CHC13 molecules in the unit cell, have been obtained. In both cases the monoaurated diacylamido complex C6H4(CO)2N(AuPPh3) (1) is present as a monomer with linear two-coordinate gold atoms. The N -A u(I) bond lengths (2.028(4), 2.040(4) A) are similar to those found in other monoaurated complexes of the type R 'R 2N(AuPPh3) with strongly electron-withdrawing organic substituents R 1, R2. Crystal data: 1, monoclinic, P 2t/c, a = 9.948(1), b = 15.712(1), c = 14.651(1) Ä, ß = 103.40(1)°, V = 2227.7 Ä3, Z = 4; 1CH C13, orthorhombic, P 212,21, a = 8.889(1), b = 10.349(1), c = 29.198(2) A, V = 2686.0 A3, Z = 4.

Gold complexes and nanoparticles exhibit fascinating properties and have found various applications recent years. The chemistry of gold, significantly different from that of its congeners (silver and copper), is mostly dominated by its extraordinarily strong relativistic effects, which impose a very small energy gap between its 5d and 6s valence orbitals and, consequently, a high degree of sd h...

The compounds Re2(CO)8(μ-AuPPh3)2, 1, a dimer of Re(CO)4(μ-AuPPh3), and ax,ax-Re2(CO)8(PPh3)2 were obtained from UV−vis radiationinduced decarbonylation of the compound Re(CO)5[Au(PPh3)]. Compound 1 contains two rhenium atoms bridged by two AuPPh3 groups. The complex has 32 valence electrons and is formally unsaturated by the amount of two electrons. The Re−Re bond distance in 1 is unusually sh...

The difficulty in generating 1,4-Li2-C6H4 utilising the lithium halogen exchange reaction on 1,4-Br2-C6H4, 1,4-I2-C6H4 and 1-Br-4-I-C6H4 is revisited and only on treatment of 1,4-I2-C6H4 with 2 molar equivalents of n-BuLi can 1,4-Li2-C6H4 1 be isolated in excellent yield. Treatment of 1 with two equivalents of [ClAu(PPh3)] gives [1,4-(Ph3PAu)2-C6H4] 2a in excellent yield. Subsequent treatment o...
