1iodo2methylpropane

1-Iodo-2-methylpropane, also known as isobutyl iodide, is an organoiodine compound with the chemical formula (CH3)2CHCH2I. It is a colorless liquid at room temperature. Its structure consists of a propane chain with a methyl group attached to the second carbon and an iodine atom attached to the first carbon. This arrangement makes it a primary alkyl halide.

1-Iodo-2-methylpropane is typically prepared through the reaction of isobutyl alcohol with a suitable iodinating agent, such as phosphorus triiodide or a mixture of iodine and red phosphorus. It can also be synthesized via the Finkelstein reaction, where an alkyl chloride or bromide is treated with sodium iodide in a polar aprotic solvent like acetone.

As a primary alkyl halide, 1-iodo-2-methylpropane participates in nucleophilic substitution reactions. It is a reactive compound and can be used as a starting material or intermediate in organic synthesis for the introduction of the isobutyl group into other molecules. Its reactivity is generally higher than that of the corresponding chloride or bromide due to the weaker carbon-iodine bond.
