Synthesis and Reactivity of Selones and Dihaloselones: Complexation of Selones with d8- and d10-Metal Ions

The reactivities of the monodentate selone LSe (L = 1,3-dibutylbenzimidazol-2-ylidene; 10a), the bidentate pyridine-functionalized selone L′Se (L′ = 1-pyridyl-3-butylimidazol-2-ylidene; 10b) and the multidentate ether-functionalized selone L′′Se {L′′ = 1,3-bis[2-(2-methoxyethoxy)ethyl]benzimidazol-2-ylidene; 10c} with soft transition-metal halides (PdX2, PtX2, ZnX2, CdX2 and HgX2; X = Cl, Br, I) are probed. Compounds 10a and 10c react with metal halides to give complexes of the type [Cu2(μ-X)2(LSe)2] (X = Br, I; 11, 12), [MX2(LSe)2] (13–22) or [M2X2(μ-X)2(L′′Se)2] (X = Cl, Br, I; 26–32), whereas 10b and HgX2 (X = Cl, Br, I) form 1:1 complexes HgX2(L′Se) (21–23), in which the pyridine moiety coordinates to the metal centre to form a six-membered chelate. The reactivity of 10a was compared with those of triphenylphosphine and triethylamine. The reaction of 10c with molecular iodine yields the diiodoselone L′′SeI2 (35), which disproportionates to give the selone adduct of the iodonium ion, [(L′′Se)2I]+I3– (36). The reactions of LSeX2 [X = Cl (34a), Br (34b), I (34c)] with organotellurium compounds, namely, tellone LTe (10d) and diphenyl telluride (37), afford the dihalotellones LTeX2 [X = Cl (38a), Br (38b), I (38c)] and Ph2TeX2 [X = Cl (39a), Br (39b), I (39c)], respectively. The oxidizing properties of LSeX2 (34a–34c) were investigated with rare-earth metals.

Thermal decomposition of complexes of cadmium(II) and mercury(II) with triphenylphosphanes

A series of substituted triphenylphosphane complexes of the type CdL 2X2 (L= triorthotolylphosphane or trimetatolylphosphane; X=Cl-, Br- or I-) and HgL2X 2 (L=triphenylphosphane or triorthotolylphosphane) was prepared fresh. The thermal decomposition was carried out in air with heating rate programmed at 10°C min-1 and it revealed that the complexes with ortho derivative were less stable and the triphenylphosphane moiety leaves along with halogen in the first step. All the complexes were stable up to 210°C. However, the stability order of the tetrahedral complexes was X=Cl>Br. Values of n, E, lnA and ΔS # have been approximated and compared. Complexes having Br have higher E a, lnA and ΔS # values than that having Cl.

Chemical dissection and reassembly of a mixed-metal cluster, Hg9Co6(CO)18

The cluster Hg9Co6(CO)18 reacts with compounds of type HgX2 to form new monocobalt compounds, (CO)3Co(HgX)3 (X = I, Cl, O2CCF3). The iodo derivative was used to prepare (CO)3Co(HgI)3I- Bu4N+, (CO)3Co(HgO3SC6H4CH 3)3, and (CO)3Co(HgPh)3. Addition of PPh3 to (CO)3Co(HgCl)3 caused reassembly of Hg9-Co6(CO)18 in high yield.

Solid-state 31P CP-MAS NMR study of phosphine complexes of mercury(II)

The solid-state 31P CP-MAS NMR spectra of several phosphine complexes of mercury(II) with known crystal structures have been measured. In addition, some simple valence bond calculations were performed and an attempt was made to relate calculate
