The Front Cover illustrates the photocatalytic reduction of CO2 to CO by an aniline-substituted Re-bipyridine-type photocatalyst in presence a strong electron donor (1,3-dimethyl-2-phenyl-2,3-dihydro-1H-benzo[d]-imidazole=BIH) N,N-dimethylacetamide. This catalyst absorbs visible light intensely compared related catalysts, and aniline moiety has beneficial effect on activity. More information ca...

3-Methyl-5-chloro-1-phenylpyrazol and its derivatives were prepared by the reaction with 3methyl -1-phenylpyrazol-5-one, phosphorous oxytrichloride and N-N dimethyl aniline respectively using catalyst. These compounds were further treated with alcohols and sodium hydroxide to form ether linkage. Ethyl acetoacetate reacted with phenylhydrazine at reflux temprature to give 3-methyl-1phenylpyrazol...

Acridinediones were synthesized by the one-pot Hantzsch condensation of an aromatic aldehyde, 5,5-dimethyl-1,3-cyclohexanedione, and aniline/4-methylaniline in refluxing water. This method has then been extended to the four-component reaction of an aromatic aldehyde, 5,5-dimethyl-1,3-cyclohexanedione, ethyl acetoacetate and ammonium acetate for the synthesis of polyhydroquinoline derivatives. Th...

We have developed a new technology called multi-catalysis for the sequential one-pot synthesis of highly functionalized heterocycles. A practical and novel multi-component aniline-, self- and Brønsted acid-catalyzed selective process for the sequential one-pot synthesis of highly substituted 2-(2-hydroxy-aryl)-cyclopentane-1,3-diones, 3,9-dihydro-2H-cyclopenta[b]chromen-1-ones and 3,3-dimethyl-...

The title compound, C(15)H(16)N(2), contains two aromatic rings linked through an imino group. The mol-ecule exhibits an E configuration with respect to the C=N bond. The dihedral angle between the aromatic rings is 61.96 (1)°.

In the title compound, C(18)H(21)NO(3), the C=N bond has a trans conformation and the benzene rings are oriented at a dihedral angle of 61.32 (6)°. The C atoms of the three meth-oxy groups are all roughly coplanar with their attached ring [deviations = 0.219 (2), -0.097 (2) and -0.137 (2) Å]. In the crystal, a weak C-H⋯π inter-action may help to establish the packing.
