The title compound, C(18)H(23)N(2)Si(+)·Cl(-)·H(2)O, was synthesized from 1-[(trimethyl-sil-yl)meth-yl]benzimidazole and benzyl chloride in dimethyl-formamide. The benzimidazole ring system is approximately planar, with a maximum deviation of 0.022 (2) Å, and makes an angle of 74.80 (12)° with the phenyl ring. The crystal packing is stabilized by O-H⋯Cl, C-H⋯Cl, C-H⋯O and C-H⋯π inter-actions be...
The title compound, C(24)H(21)N(3)O, was prepared by the reaction of (Z)-2-(1H-indol-3-ylmethyl-ene)-1-aza-bicyclo-[2.2.2]octan-3-one with α-bromo-p-toluonitrile, under phase-transfer catalytic (PTC) conditions using triethyl-benzyl-ammonium chloride and 50% w/v aqueous NaOH solution in dichloro-methane. The crystal structure indicates the presence of a double bond with Z geometry connecting th...
[reaction: see text] A highly diastereoselective anti aldol addition utilizing a variety of N-glycolyloxazolidinethiones has been developed. Enolization of an N-glycolyloxazolidinethione with titanium (IV) chloride and (-)-sparteine followed by addition of an aldehyde activated with additional TiCl(4) resulted in highly anti-selective aldol additions, typically with no observable syn isomers. A...
In the title compound, [NiCl(2)(C(10)H(10)N(2))(4)], the Ni(II) ion is located on an inversion center being coordinated by four N atoms from two pairs of symmetry-related 1-benzyl-1H-imidazole ligands and two chloride anions in a distorted octa-hedral geometry. Weak inter-molecular C-H⋯Cl hydrogen bonds link the mol-ecules into layers parallel to the ab plane.
New biodegradable surface active agents were prepared by glycosidation of prehydrolysis lignin with the D-glucose using anhydrous ferric chloride as the catalyst which afforded polymeric alkyl, benzyl and aryl glucofuranoside derivatives of lignin. Moreover, a series of novel lignin-based surface active agents was obtained by subsequent Oxidation of the primary alcohol groups of u-glucose into ...
[N,N-Bis(diphenylphosphanyl)benzylamine-κ2 P,P′]dichloridonickel(II) dichloromethane monosolvate
In the title solvated complex, [NiCl(2)(C(31)H(27)NP(2))]·CH(2)Cl(2), the Ni(2+) ion is coordinated by two chloride ions and two P atoms of the chelating N,N-bis-(diphenyl-phosphan-yl)benzyl ligand to generate a strongly distorted cis-NiCl(2)P(2) square-planar geometry for the metal ion. In the crystal, the components are linked by C-H⋯Cl inter-actions.
The aim of the present study was to synthesis a series of phthalimides based on our previous works and examine their anxiolytic properties. Using a three steps process, phthalimides were prepared from the corresponding di-methyl phthalate derivatives. Phthalic anhydride was nitrated to produce 3-nitrophthalic acid. Ring closer of either 3-nitrophthalic acid or di-methyl phthalate with urea were...
In the presence of K(2)CO(3) in refluxing THF, dichloro-substituted tetraoxacalix[2]arene[2]triazine, a readily available macrocyclic compound from cyanuric acid chloride and benzyl 1,3-dihydroxybenzoate, underwent highly efficient nucleophilic displacement reactions with bis-nucleophilic reagents of different geometry, length and chirality in a 2+2 fashion to produce large and size-tunable cav...
The title compound, C(25)H(24)N(2)O(3) was prepared by the reaction of (Z)-2-(1H-indol-3-ylmethyl-ene)-1-aza-bicyclo-[2.2.2]octan-3-one with methyl p-(bromo-meth-yl)benzoate, under phase-transfer catalytic (PTC) conditions using triethyl-benzyl-ammonium chloride and 50% w/v aqueous NaOH solution in dichloro-methane. The crystal structure indicates the presence of a double bond with Z geometry c...
The asymmetric unit of the title salt, C(28)H(28)O(3)P(+)·Cl(-)·H(2)O, contains a benzyl-triphenyl-phospho-nium cation, a chloride counter-ion, and a water mol-ecule of crystallization. The 3,4,5-trimeth-oxy substituents of the benzylic functionality are arranged with the 3,5-methyl groups lying approximately in the aromatic ring plane while the 4-methyl group is out of the plane.
