Efficient Regioselective Iodination of Pyrazole Derivatives Mediated by Cadmium(II) Acetate
ChemistryOpen, EarlyView.The iodination reactions of both N, C alkyl‐, propargylic substituted and unsubstituted pyrazole derivatives initiated by cadmium (II) acetate were performed. It was revealed that the C‐4 position of the pyrazole ring was more nucleophilic. The nucleophilicity of the pyrazole ring significantly increased due to the influence of alkyl groups and ...

ChemistryOpen, EarlyView.New tellurium‐containing tetrahydropyrazolo[1,2‐a]pyridazines and dihydropyrazolo[1,2‐a]pyrazoles were obtained by electrophilic heterocyclization in the form of intramolecular salts, and optimal conditions for their synthesis were found. The heterocyclization process is regio‐ and stereoselective, which is confirmed by spectral studies, and by X‐ray ...
