Tris(2,4-dimethyl-benzene-thiol-ato)phenyl-tin(IV).

In the title compound, [Sn(C(6)H(5))(C(8)H(9)S)(3)], the Sn atom has an approximately tetra-hedral SNCS(3) geometry, with angles at this atom ranging from 105.13 (3) to 113.54 (9)°. The crystal packing does not involve any significant inter-molecular inter-actions, although the benzene rings are involved in a number of weak intra- and inter-molecular C-H⋯π inter-actions.

Template-controlled synthesis of a planar [16]ane-P2C(NHC)2 macrocycle.

Reaction of tetraphosphine platinum(II) complexes with 2-azidoethyl isocyanide 3 in methanol leads to complexes with two trans-coordinated NH,NH-stabilized carbene ligands 6(X)(2). Complexes 6(X)(2) react with phenyldivinylphosphine under substitution of the remaining phosphine ligands followed by an intramolecular hydroamination reaction to produce complex 1(PF(6))(2) with a macrocyclic [16]ane-P(2)C(NHC)(2) ligand.

Synthesis of NHC complexes by template controlled cyclization of beta-functionalized isocyanides.

Starting from complexes of type [Ru(Cp)Cl(P-P)] (P-P = 2PPh3, 3a; P-P = 2PMe3, 3b: P-P = dppe, 3c; P-P = dppp, 3d) isocyanide complexes [Ru(Cp)(P-P)(CNR) 4a-4d (CNR = CN-CH2-CH2N3, 1) and 7a-7d (CN-C6H4-2N3, 2) have been prepared. Reduction of the azido functions of the coordinated isocyanide ligands with Zn/NH4Cl/H2O in methanol leads to coordinated 2-amino functionalized isocyanides which cyclize to yield the complexes with a saturated NH,NH-stabilized NHC ligand 5a-5d or a benzannulated NH,NH-stabilized NHC ligand 8a-8d. The Zn/NH4Cl/H2O reduction method is of general applicability and allowed the generation of complex 11 bearing three saturated NH,NH-stabilized NHC ligands.

Electrochemical behavior of an aminotrithioether ligand: copper(II)-mediated oxidative C-C bond formation.

A neutral aminotrithioether interacts with CuI, generating a coordination polymer in the solid state. Electrochemical studies indicate that the ligand is prone to oxidation by CuII, which results in a novel C-C bond formation reaction.

O-(2-tert-butyl-6-dimethylthiocarbamoyl-4-methylphenyl) N,N-dimethylthiocarbamate dichloromethane solvate.

In the title compound, C(17)H(26)N(2)OS(2).CH(2)Cl(2), the C=S distances are 1.650 (4) and 1.679 (3) A, and the torsion angle between the planes of the thiocarbamate and carbonothioyl fragments is 54.4 (2) degrees. The steric and electronic effects that these substituents exert on one another determine the observed anti configuration with respect to the phenyl C atoms to which they are attached.
