一般說明

二碘甲烷是一种溶剂,可用作形成金属卤化物的卤键供体。

二碘甲烷(CH2I2)是一种含碘的有机化合物。 通过在310nm处光引发,它在乙腈中的分解已有研究。通过飞秒泵浦探针光谱和从头分子动力学模拟对CH2I2的光分解研究表明,该过程可产生二碘甲烷的异构体(CH2I-I)作为热光产物。在大气中,它可在臭氧存在下进行光解,并产生碘氧化物(IO),该过程会导致形成气溶胶。其真空紫外(VUV)光吸收光谱已有报道。

應用

二碘甲烷可用作接触角测量中的探针溶剂,以分析聚合物表面的亲水性。
二碘甲烷已被用作探针液,用于评价儿茶酚胺涂覆的纤维表面的表面能的极性和分散组分。它可用于制备环丙基酮、酯和酰胺。

In this paper, the biomineralization potential and cellular response of novel blend films of the anionic sulfated polysaccharides kappa-carrageenan (KCG) and fucoidan (FUC) derived from seaweeds with semi-crystalline polyhydroxybutyrate (PHB) and polyhydroxybutyrate-co-valerate (PHBV), respectively, were analyzed. The incorporation of KCG

Photodissociation of diiodomethane (CH2I2) in acetonitrile solution has been studied with ab initio molecular dynamics simulations, which show how the iso-diiodomethane photoproduct (CH2I-I) can be formed. The first excited state, described by the "restricted open-shell Kohn-Sham" density functional method, is

The electronic absorption spectrum of diiodomethane in the 30,000-95,000 cm(-1) region is investigated using synchrotron radiation; the spectrum in the 50,000-66,500 cm(-1) region is reported for the first time. The absorption bands in the 30,000-50,000 cm(-1) region are attributed to
Nickel-catalysed cyclopropanation of electron-deficient alkenes with diiodomethane and diethylzinc.
