An iodo-substituted product with triple bond is more reactive and prone to further electrophilic iodination forming a triiodo-substituted derivative. The introduction of methyl groups in the pyrazole ring of derivatives with propargylic substituent contributed to the promotion of competitive iodination reactions due to the increase in nucleophilicity of the pyrazole ring.
