Description

General description

Iodomethane (Methyl iodide) is a colorless liquid. It can be prepared by reacting dimethyl sulfate with concentrated KI. Reaction of iodine and phosphorous with methanol has been reported to afford iodomethane. It reacts with tris(triphenylphosphine)chlororhodium(I) to afford the octahedral complex of rhodium(III), [RhlCl(CH₃)(PPh₃)₂(ICH₃)]. Kinetics of its reaction with atomic chlorine in the gas phase has been investigated. The absolute rate constant of the reaction has been reported.

Application

Iodomethane (Methyl iodide) may be employed in the preparation of stable neutral solutions of hypoiodous acid and various methyl esters.
