4-Iodobenzoyl chloride
4-Iodobenzoyl chloride (CAS: 1711-02-0) is an organic acid halide with the molecular formula IC6H4COCl and a molar mass of 266.46 g/mol. This compound serves as a versatile building block in organic synthesis. Its applications include the modification of polymers, the preparation of potential pharmaceutical agents targeting dopamine receptors, and the synthesis of advanced materials like rotaxanes and pyrroles.

Polymer Modification
4-Iodobenzoyl chloride has been utilised to modify poly(allylamine), rendering the polymer X-ray visible. This application is valuable in materials science for creating radiopaque polymers.
Dopamine D4 Antagonist Preparation
It is employed in the synthesis of N-(1-benzylpyrrolidin-3-yl)arylbenzamide derivatives. These compounds have been investigated for their potential as human dopamine D4 receptor antagonists.
Rotaxane Synthesis
The compound serves as a monomer for the preparation of [2] rotaxane structures, which are essential precursors for the synthesis of poly[2] rotaxanes.
Pyrrole Synthesis
4-Iodobenzoyl chloride participates in palladium-catalysed synthesis of pyrroles from imines and acetylenes via isocyanide mediation, a key reaction in heterocyclic chemistry.
