The synthesis, IR and 31P NMR spectra of the complexes of various N-aryltriphenylphosphinimines with some mercury dihalides as well as the corresponding phosphonium salts are reported. It is shown by an X-ray crystal structure analysis of the complex of the unsubstituted phosphinimine with HgCl2 that in the solid state these complexes form dimers via two Hg ∙∙∙ μ2- Cl ∙∙∙ Hg bridges.

Abstract Monomerie diiodides of 2,4,6-tri(tert-butyl)phenyl = (s-Mes), 2,4,6-triisopropylphenyl = (Trip)-and 2,4-di-tert-butyl-6-methylphenyl = (DBMP)-gallium and -indium were prepared by the reaction of the lithiated aryls with MI3 (M = Ga, In) in hexane/Et2O. s-MesInI2 (1), s-Mes2InI (2), s-MesGaI2 (3), s-Mes2GaI (4), Trip2InI (5) and (DBMP)2InI (6) were obtained and characterized by their mass and NMR spectra (1H, 13C), and/or by elemental analyses. An X-ray crystal structure analysis was carried out for 1.

Reactions of 4-hydroxycoumarin (1a) and 4-chlorocoumarin-3-carbaldehyde (1b) with amino alcohols or alkylene diamines led to the formation of the corresponding N-substituted 4-aminocoumarins 3, 5 and 6. However, 4-hydroxycoumarin-3-carbaldehyde (8) reacted with 2-aminoethanol and ethylenediamine to give N-substituted 3-(aminomethylene)-chromane-2,4-diones 9a, b. The structure and the E-configuration of compound 6 were proven by X-ray crystal structure analysis. Products 9a, b displayed signals of both E- and Z-isomers in their NMR spectra. All novel products have been characterized by means of spectral (IR, NMR, MS) data and elemental analyses

Solid State Structures

The compounds 1,3-bis(diethylgallyl)benzene (3) and 1,4- bis(diethylgallyl)benzene (6) were prepared by reaction of the corresponding chloromercuriobenzenes with an excess of triethylgallium by applying pressure and higher temperatures. These compounds very easily undergo redistribution reactions in solution and in the solid state. Extremely air-sensitive crystals suitable for an X-ray crystal structure analysis were obtained from triethylgallium as solvent. The structural studies revealed the presence of tetra-coordinated carbon and gallium atoms in symmetric aryl-diethylgallyl bridging units. The coordination behavior of 3 and 6 in the solid state is quite different from that of the corresponding methyl-substituted compounds

Triazine Derivatives

The reactions o f 2-hydro-1,3,5-trim ethyl-1,3,5-triaza-2-oxo-2λ4 -phosphorinan-4,6-dione 1 with the triazine derivatives, 1,3,5-trimethyl- and 1,3,5-tribenzyl-hexahydro-1,3,5-triazine, are described. The reaction of three equivalents of 1 with one equivalent of the triazine derivative gave 2 and 3. Both compounds were characterized via their 1H, 13C, and 31P NMR spectra, mass spectra and, in the case of 2, by an X-ray crystal structure analysis, which showed an almost planar six-membered ring; hydrogen bonds of the form N-H···O link the molecules in centrosymmetric pairs. The reactions of 1 with the aldehydes glyoxylic acid, 2-hydroxybenzaldehyde and 3,4,5-trimethoxybenzaldehyde gave addition products. The C (:O) group o f the aldehyde is inserted into the P -H bond o f 1. The resulting compounds 4 ,5 and 6 were characterized through their 1H, 13C, and 31P NMR spectra, and mass spectra.

Complex Fragment

Abstract Reaction of the tetrahydrofuran-stabilized 16-electron complex fragment [Cp*Re(CO)2] with dimethyl disulfide, MeSSMe, leads to the diamagnetic title compound, Cp*Re(CO)(SMe)2 , which was characterized by mass, IR and NMR spectra and by an X-ray crystal structure analysis**. The two methylsulfido ligands are bent (angles Re-S-CH3 114.1(3)°) and turned away from the Cp* ring. The Re - S-bond distances are 227.0(2) pm.
