Description

Certain peculiarities of oxidative iodination of substituted N-methyl pyrazoles by the mixture of I2 ad HIO3 are studied. Compounds, containing substituents in position 3 and (or) 5 are halogenated in free position 4. Iodination of 3-acetyl-1.5-dimethylpyrazole is accompanied by partial halogenation of acetyl group. 4-benzoylpyrazole undergoes ipsosubstitution. Strong electron acceptor substituents (NO2) in position 4 hamper iodination. The iodination products are identified using the methods of IR and PMR spectroscopy, their yields and melting points being determined
