General description
Diiodomethane (CH2I2) is an iodine containing organic compound. Its decomposition in acetonitrile initiated by 310nm light has been investigated. Femtosecond pump-probe spectroscopic and ab initio molecular dynamics simulations studies of the photodecomposition of CH2I2 suggest the formation of the isomer of diiodomethane (CH2I-I) as hot photoproduct.[1][2] In the atmosphere, it undergoes photolysis in the presence of ozone to afford iodine oxide (IO) which results in the formation of aerosols. Its vacuum ultraviolet (VUV) photoabsorption spectrum has been reported.
Application
Diiodomethane has been used as a probe liquid for evaluation of the polar and dispersive components of the surface energy of the catecholamine coated fiber surfaces. It may be used for the preparation of cyclopropyl ketones, esters and amides.
Diiodomethane may be used as a probe solvent in contact angle measurement to analyze the hydrophilicity of polymer surfaces.
