Synthesis of Cinnamylideneacetic Acid by Perkin Reaction

Synthesis of fatty acid anhydrides by reaction with dicyclohexylcarbodiimide.

A simple method is described for the preparation of caprylic, palmitic, stearic, and oleic anhydrides. Reaction of the free fatty acid and dicyclohexylcarbodiimide in carbon tetrachloride at room temperature gives the corresponding anhydrides in high yield (87-94%).

Synthesis & Characterization of CaB4O7 Powder by Solid-State Reaction

The synthesis of calcium tetraborate was investigated in a temperature ranging from 800℃ to 900℃ using the solid-state reaction method. The synthesis was done using ammonium tetraborate tetrahydrate as the source of boron. At temperatures of 800 ℃ and 880 ℃, the mixed phases from different compounds were formed. At the optimum temperature of 840℃, the mixed phase was only composed of meta and t...

Amino acid synthesis by reversal of the amino acid oxidase reaction.

Although the intermediate formation of an imino acid is consistent with available data, direct experimental evidence for it is still lacking. The reaction in the presence of air proceeds to completion and is essentially irreversible because of reoxidation of the reduced flavoenzyme by molecular oxygen. Previously, the amino acid oxidase reaction has been studied only in the direction of cr-keto...

Microwave Assisted Synthesis of N-Benzylenaminones Catalyzed by Chloroacetic acid

Benzylaminoalkenones and benzylaminoalkenoates 3 were synthesized from reaction of benzylamine with corresponding 1,3-diketones and 1,3-ketoesters in the presence of catalytic amount of chloroacetic acid under microwave radiation. This method offers several advantages including high yield of products, recyclable of the catalyst and easy experimental work-up procedure.
