After reading the article, we found that the author used 1-Chloro-3-iodobenzene(cas: 625-99-0Electric Literature of C6H4ClI)

1-Chloro-3-iodobenzene(cas: 625-99-0) belongs to organic iodides.Electric Literature of C6H4ClI The carbon-iodine bond is weaker than other carbon-halogen bonds due to the poor electronegative nature of the iodine atom. In general, organic iodides are light-sensitive and turn yellow during storage, owing to the formation of iodine.

After six key consecutive reactions, including a diastereoselective step, 2-quinolinone-fused γ-lactones were obtained in good overall yield (up to 46%; 10 s). In addition to this study using 4-Chloro-2-iodoaniline, there are many other studies that have used 4-Chloro-2-iodoaniline(cas: 63069-48-7COA of Formula: C6H5ClIN) was used in this study.

4-Chloro-2-iodoaniline(cas: 63069-48-7) belongs to anime. The reaction of alkyl halides, R―X, where X is a halogen, or analogous reagents with ammonia (or amines) is useful with certain compounds. Not all alkyl halides are effective reagents; the reaction is sluggish with secondary alkyl groups and fails with tertiary ones. Its usefulness is largely confined to primary alkyl halides (those having two hydrogen atoms on the reacting site).COA of Formula: C6H5ClIN

The title of the article was 《Additive scheme of solvation enthalpy for halogenated aliphatic hydrocarbons at 298.15 K.》.Recommanded Product: 624-73-7 The author mentioned the following in the article:

In this work, an additive scheme for the estimation of solvation enthalpy of halogenated aliphatic hydrocarbons in n-heptane was developed. The proposed structural fragments for halogen group contributions are dependent on the nature of neighboring atoms. A linear relationship between solvation and vaporization enthalpy at 298.15 K for mono- and di-α,ω-halogen aliphatic compounds was found. These relationships can be used for the quick estimation of standard vaporization and solution enthalpies at 298.15 K. Proposed approaches for estimation of solvation, solution and vaporization enthalpies at 298.15 K were verified by conventional methods. In most cases, absolute deviations between exptl. and estimated values for halogenated aliphatic hydrocarbons do not exceed 1-2 kJ mol-1. In addition to this study using 1,2-Diiodoethane, there are many other studies that have used 1,2-Diiodoethane(cas: 624-73-7Recommanded Product: 624-73-7) was used in this study.
