Synthesis of Some Aryl Chalcones Using Silica-Sulphuric Acid Reagent under Solvent Free Conditions
E-Journal of Chemistry, 2007 There are two series of α, β-unsaturated ketones derived form Biphenyl and 9H-Fluorenyl, and ketones with various substituted benzaldehydes under solvent free conditions using silica-sulphuric acid as a reagent in an oven. The catalyst silica is reusable

4-(p-Tolylamino)benzaldehyde [PDF]
Acta Crystallographica Section E Structure Reports Online, 2010 In the title compound, C(14)H(13)NO, the dihedral angle between the aromatic rings is 66.08 (9)°. Chains are formed along the b axis through inter-molecular N-H⋯O hydrogen bonds. The crystal structure is further stabilized by C-H⋯π inter-actions.

Synthesis of Schiff Bases via Environmentally Benign and Energy-Efficient Greener Methodologies
E-Journal of Chemistry, 2009 Non classical methods (water based reaction, microwave and grindstone chemistry) were used for the preparation of Schiff bases from 3-chloro-4-fluoro aniline and several benzaldehydes. The key raw materials were allowed to react in water, under microwave

Angewandte Chemie, EarlyView.Eine divergente Aldehyd‐Funktionalisierungssequenz, ermöglicht durch ein anomeres Amid, erlaubt den Ein‐Topf‐Zugang zu unsymmetrischen Harnstoffen, Carbamaten, Thiocarbamaten, Thioestern und Amiden. Entscheidend für diese Transformation ist die Bildung von N‐Boc‐Hydroxamat‐Intermediaten, die als Plattformen für eine orthogonale Aktivierung über Lossen ...

Oxidation of benzaldehyde in some single phase betaine-benzaldehyde-water systems
Journal of Pharmacy and Pharmacology, 1964 AbstractThe oxidation rates of increasing concentrations of benzaldehyde in ternary systems of the L1 type have been measured in aqueous solutions of four betaine homologues. On applying corrections for extra-micellar material, the rate becomes independent of the betaine concentration and is related to the micellar ratio of benzaldehyde to betaine when
