1-((E)-3-(4-bromophenyl) -1-phenylallylidene)-2-(m-tolyl)hydrazine (4) was synthesized and characterized for structural elucidation by spectroscopy (FT-IR, 1H NMR, and 13C NMR) and single crystal X-ray diffraction. In the title compound, the benzene rings A, B, C were oriented at dihedral angles...

The mechanism of homolytic triphenylmethylation of aromatic substrates has been studied by the reaction between diacyl peroxide and triphenylmethyl free radical in toluene, anisole and chlorobenzene. A previously proposed mechanism, involving acyloxycyclohexadienyl radical as intermediate, has b...

When studying polymerization in the presence of bis-triphenylmethyl barium (TPM-Ba) in THF the effect of the type of alkyl group combined with the initiator on elementary stages of chain extension was established for the first time for processes of anionic polymerization initiated by non-transit...

Incorporation of fluorinated heterocyclic framework into organic molecules results in profound changes in their physical, chemical and biological properties. Realizing that the fluorinated thiochroman-4-ones are important scaffolds in medicinal chemistry and are rare in the chemical literature, ...

Reactions of tetraphenylantimony mercaptides, Ph4SbSC6H4Y, with electrophilic species in chlorocarbon solutions are reported. With chloromethyl methyl sulphide, allyl halides, sulphenyl halide, acyl halides, halogens, and triphenyltin chloride, ready and complete halide—mercaptide exchanges occ...

A series of tri- and tetraphenylantimony(V) compounds containing arylcarbonyloxy moiety have been synthesized and characterized by elemental analysis, IR, and NMR spectroscopy. Attempts to grow crystals led to colorless blocks identified by X-ray diffraction as (ArCOO)2SbPh3 or (ArCOO)SbPh4.

Single crystals of anhydrous strontium oxalate have been prepared by hydrothermal synthesis in the presence of divalent transition metal ions. Strontium is eight coordinate with approximate square antiprismatic geometry. The SrO8 polyhedra form a 3-dimensional network by sharing edges and vertic...

In this paper, strontium oxalate particles with different morphologies could be easily obtained by a precipitation reaction of sodium oxalate with strontium chloride in the absence and presence of poly-(styrene-alt-maleic acid) (PSMA). The as-prepared products were characterized with scanning el...

Single crystal of a novel metal organic nonlinear optical (NLO) cadmium (II) dibromide l - proline monohydrate (CBLPM) of size 7 × 7 × 5 mm3 was grown from slow evaporation technique. Single crystal X – ray diffraction analysis reveals that the crystal belongs to orthorhombic system with latt...

Strontium-substituted β-TCP with the general formula Ca(3−x)Srx(PO4)2 (0

Strontium titanate nanocube-dispersed mesoporous silica (STO(NC)-MPS) nanocomposite was examined as a photocatalyst for the photoreduction of CO2. Copper (Cu) was examined as a co-catalyst, and the results showed that it was effective for the production of CO under a flow of CO2 and UV irradiati...

The crystal growth and dissolution of strontium oxalate monohydrate have been studied at 25°C by following the changes in electrical conductivity of supersaturated and subsaturated aqueous solutions seeded with aged crystals of the monohydrate salt. Both processes follow a kinetic equation in w...

Undoped and Eu3+ doped monohydrate strontium oxalate samples were precipitated under ultrasound and conventional stirring and were heated at different temperatures. All samples were characterized by X-ray powder diffraction (XDR), infrared spectra (IR) and scanning electron microscopy (SEM). Mon...

In order to promote bone healing, new generations of biomaterials are under development. These biomaterials should demonstrate proper biological and mechanical properties preferably similar to the natural bone tissue. In this research, 3D-printed barium strontium titanate (BST)/β-tricalcium pho...

The present communication deals with the synthesis, single crystal growth and characterization of a new nonlinear optical material l-proline strontium chloride monohydrate (l-PSCM). Single crystals have been grown using the slow solvent evaporation technique. Single crystal XRD analysis confirme...

The crystal structure of methyltin triiodide (CH3SnI3) has been determined by single crystal X-ray diffraction. It belongs to the orthorhombic space group Cmc21, with a 10.3421(15), b 13.1403(15) and c 6.5700(8) Å. The CH3SnI3 molecules are found to be discrete and loosely packed in the crystall...

Publisher SummaryThe chapter discusses methyltin halides and their molecular complexes with organic ligands. The halides and their complexes are very promising for the study of the chemistry of organometallic and complex compounds, throwing light on the problem of solvent effects on the kinetics...

Concentrations of total recoverable inorganic tin (TRISn), monomethyltin (MeSn3+), dimethyltin (Me2Sn2+), trimethyltin (Me3Sn+) and (3-dimethylsulphonio)propionate (DMSP) were determined in leaves of Spartina alterniflora from three sites in the Great Bay estuary (NH) from 8 May to 15 September ...
