2Iodonaphthalene

2-Iodonaphthalene is an organic compound with the chemical formula C10H7I. It is a derivative of naphthalene, a polycyclic aromatic hydrocarbon, where one hydrogen atom has been replaced by an iodine atom. This compound is a white to off-white crystalline solid at room temperature. It is soluble in organic solvents such as ethanol, acetone, and benzene, but insoluble in water.

2-Iodonaphthalene is primarily used as an intermediate in the synthesis of other organic compounds. Its iodine atom can be substituted with various functional groups through nucleophilic substitution reactions, making it a valuable reagent in organic synthesis. It is also used in the production of certain dyes and pigments.

The synthesis of 2-iodonaphthalene typically involves the halogenation of naphthalene using iodine in the presence of a catalyst. The reaction proceeds via an electrophilic aromatic substitution mechanism, where the iodine molecule attacks the naphthalene ring to form the iodinated product.

2-Iodonaphthalene is a hazardous substance and should be handled with care. It is toxic if swallowed, inhaled, or absorbed through the skin. Prolonged exposure can cause skin irritation and eye damage. Appropriate personal protective equipment, such as gloves, safety glasses, and lab coats, should be worn when handling this compound. It is also important to dispose of it according to local regulations to prevent environmental contamination.
