A series of Nـ alkyl 2ـ ketomethylquinoline derivatives were synthesis by reaction of benzoyl chloride derivatives with Nـ methyl quinaldine iodide in the presence of triethyl amine under microwave irradiation. Enaminone form of the product study by spectroscopy method. The result revealed the  Nـ alkyl 2ـ ketomethylquinoline the fixed enaminone tautomer.

The title compound, 2[Ce(C(51)H(75)N(4)O(3))]·C(4)H(10)O, was obtained in high yield (92%) by reduction of (TRENDSAL)Ce(IV)Cl [TRENDSAL is N,N',N''-tris-(3,5-di-tert-butyl-salicyl-ide-natoamino)-triethyl-amine] with potassium in THF. The bulky tripodal TRENDSAL ligand effectively encapsulates the central Ce(III) cation with a Ce-N(imine) distance of 2.860 (2) Å and an average C-N(amine) distanc...

The reaction between trimethylamine with propargyl bromide was studied and the structure of triethyl propargyl ammonium bromide was illustrated by 1HNMR, IR, and Mass spectra.

The crystal structure of the title diprotonated diacetyl-triethyl-ene-tetra-mine (DAT) perchorate salt, C(10)H(24)N(4)O(2) (2+)·2ClO(4) (-), can be described as a three-dimensional assembly of alternating layers consisting of diprotonated diacetyl-triethyl-ene-tetra-mine (H(2)DAT)(2+) strands along [100] and the anionic species ClO(4) (-). The (H(2)DAT)(2+) cations in the strands are connected ...

In this study we report the synthesis of a series 2-Azetidinones from N-(4-(5-bromothiophen-2-yl)-6-(4-chlorophenyl)pyrimidin-2- yl)-1-(aryl) methanimine. A mixture methanimine and triethyl amine was reacted with chloroacetyl chloride in 1,4-dioxane. The N-(4-(5-bromothiophen-2-yl)-6-(4 -chlorophenyl) pyrimidin-2- prepared reaction 4-(5-bromothiophene-2-yl)-6-(4-chloropheneyl)pyrimidin-2-amine ...

The title compound, C(17)H(18)N(2)O(2)S, was synthesized by aryl-sulfonyl-ation of 1-hy-droxy-methyl-1H-benzimidazole in the presence of triethyl-amine. The benzimidazole and benzene rings form a dihedral angle of 84.1 (1)°. The tert-butyl group was treated as rotationally disordered over two orientations in a 0.51 (2):0.49 (2) ratio. In the crystal, weak inter-molecular C-H⋯O hydrogen bonds li...

Hydrazonyl bromides 2a,b reacted with active methylene compounds (dibenzoylmethane, acetylacetone, ethyl acetoacetate, phenacyl cyanide, acetoacetanilide, ethyl cyanoacetate, cyanoacetamide and malononitrile) to afford the corresponding 1,3,4,5- tetrasubstituted pyrazole derivatives 5-12a,b. Reaction of 12a,b with formamide, formic acid and triethyl orthoformate give the pyrazolo[3,4-d]pyrimidi...

Stilbene derivatives are widely distributed in the nature and they possess various bioactivities that includes antimicrobial, antifungal, antioxidant, hepato protective, anti-HIV, cytotoxic, antiinflammatory and antiplatelet. We have synthesized novel derivatives of stilbenes by reacting various substituted phenyl acetic acid with aldehydes in presence of acetic anhydride and triethyl amine. Th...

The title compound, C(34)H(54)Br(2)N(2)O(6), was obtained by the Michael addition-elimination reaction of (5S)-5-(l-menthyl-oxy)-3,4-dibromo-furan-2(5H)-one with 1,6-hexa-nediamine in the presence of triethyl-amine. The crystal structure contains two chiral five-membered furan-one rings, in twist and envelope conformations, and two six-membered cyclo-hexane rings in chair conformations.

The title compound, C(8)H(10)ClNO(5), was obtained via a tandem Michael addition-elimination reaction of 3,4-dichloro-5-meth-oxy-furan-2(5H)-one and glycine methyl ester in the presence of triethyl-amine. The mol-ecular structure contains an approximately planar [maximum atomic deviation = 0.010 (2) Å] five-membered furan-one ring. The crystal packing is stabilized by inter-molecular N-H⋯O and ...
