Method for synthesizing aryl amidine compound through decarboxylation reaction one-pot method

The invention discloses a method for synthesizing an aryl amidine compound through a decarboxylation reaction one-pot method. The method comprises the following steps: carrying out a reaction in an organic solvent by using a compound 1 and a compound 2 as

A Convenient Synthesis of Amidines via Cycloaddition-Decarboxylation of Isocyanates and Nitrones

A base-promoted reaction between isocyanates and nitrones has been described, allowing an access to a variety of important functionalized amidines under mild reaction conditions. This strategy provides a convenient, effective, and scalable approach for the direct assembly of amidine compounds from simple starting materials in excellent yields.

Silver-Assisted [3 + 2] Annulation of Nitrones with Isocyanides: Synthesis of 2,3,4-Trisubstituted 1,2,4-Oxadiazolidin-5-ones

A silver-assisted method for [3 + 2] annulation of nitrones with isocyanides has been developed. The developed protocol allows access to a variety of 2,3,4-trisubstituted 1,2,4-oxadiazolidin-5-one derivatives as single diastereomers in good to excellent yields using silver oxide as the catalyst and molecular oxygen as the terminal oxidant. A plausible mechanism involving a nucleophilic addition/cyclization/protodeargentation/oxidation pathway is proposed on the basis of experimental results.

Highly active nano-MgO catalyzed, mild, and efficient synthesis of amidines via electrophilic activation of amides

Nano-MgO catalyzed synthesis of amidine derivatives is developed under solvent-free reaction condition at 70 C. Reusability of the catalyst and shorter reaction time as well as high yields are the advantages of this procedure.

Extraction-spectrophotometric determination of rhenium(VII) with thiocyanate and amidines in the presence of cetyltrimethylammonium bromide

A simple and selective spectrophotometric method has been developed for the determination of rhenium(VII) in the ore sample based on the reaction of ReVII with thiocyanate in the presence of tin(II) chloride in sulfuric acid media and subsequent extraction of the complex with chloroform solution of N,N′-diphenylbenzamidine (DPBA) and its nine derivatives in the presence of a cationic surfactant, cetyltrimethylammonium bromide (CTAB). The effects of acids and organic solvents on the extraction of the metal and colour intensity of the complex are discussed. The tolerance limits of diverse ions are very high. MoVI interferes it but is removed by prior precipitation by oxine effectively. The molar absorptivity and detection limit of the method with DPBA are (3.65 ± 0.02) × 104 dm -3 mol-1 cm-1 and 0.004 μg ml-1, respectively. The relative standard deviation of the method at a level of 25 μg ReVII / 10 ml is ± 1.2%.
