TL;DR: A number of new cyclometallated compounds of palladium with 2-arylpyridines have been synthesized and characterized as discussed by the authors, and the effect of varying substituents on the aryl nucleus supports the concept that after initial N-complexation, the 2-position of the anisotropic nucleus undergoes electrophilic attack by the palladium atom.

TL;DR: The square planar, macrocyclic nickel complex, N, N′-ethylenebis(salicylideneiminato)nickel(II), is shown to be an effective catalyst for the electrochemical reduction of substituted alkyl bromides; this indirect cathodic reduction can lead to a good yield of dimeric products as mentioned in this paper.

TL;DR: Experimental conditions have now been developed whereby o -bromophenyllithium(II) may be prepared in excellent yields and used as an organometallic intermediate for the synthesis of a variety of ortho bromo substituted phenyl compounds ( o -BrC 6 H 4 X) as discussed by the authors.

TL;DR: In this article, the crystal structure of the title compound, [ClMe 2 SnOSnMe 2 Cl] 2, the partial structure of its ethyl homologue and the tin-119 Mossbauer data for the two compounds in the temperature range 77-175.5 K are reported.

TL;DR: In this paper, a mechanism involving coordination of dpp via one phosphorus atom and ensuing chelation of dPP accompanied by dissociation of bpy is proposed for the ligand exchange reaction between NiMe2 (bpy) and Ph2P(CH2)3PPh2 (dpp).

TL;DR: In this article, a short account of recent work on two classes of phosphaneboranes is summarized, followed by a review of the coordination chemistry of these compounds, including diamagnetic and paramagnetic species.

TL;DR: In this paper, a study was made of the reactions of compounds of the type (Me3Si)3CSiR2X (e.g. with AgNO3i-PrOH-MeOH, a mixture of products, with Y = NO3, OMe or OPri is formed), while the compounds TsiSiR2I with R2 = Et2, PhMe, or EtMe give both rearranged products, (Me 3Si)2CH(SiMe2Y) and unrearranged

TL;DR: In this article, the allyl group in the nitrosyl complex is bound in a sigma-pi mode rather than the symmetrical mode found in the dicarbonyl.

TL;DR: In this article, the double silylation of methoxymethyldisilanes to phenylacetylene in the presence of various triphenylphosphine complexes of Ni, Rh, Pd and Pt was investigated.

TL;DR: The thermal stability and spectroscopic properties of these potentially interesting precursors in catalytic reactions are compared with those of (dipy)Ni-alkyls.

TL;DR: In this paper, the structures of (1,1′-ferrocenediyl)diphenylgermane (B) and (1 1′-phenylphosphine (C) have been determined from a three-dimensional X-ray analysis using diffractometer data.
