1-Chloro-4-iodobutane (cas: 10297-05-9) belongs to iodide derivatives. In general, organic iodides are light-sensitive and turn yellow during storage, owing to the formation of iodine. The C–I bond is the weakest of the carbon–halogen bonds. These bond strengths correlate with the electronegativity of the halogen, decreasing in the order F > Cl > Br > I. This periodic order also follows the atomic radius of halogens and the length of the carbon-halogen bond.Name: 1-Chloro-4-iodobutane

Elucidation of the Structure of a Highly Active Catalytic System for CO2/Epoxide Copolymerization: A salen-Cobaltate Complex of an Unusual Binding Mode was written by Na, Sung Jae;S, Sujith;Cyriac, Anish;Kim, Bo Eun;Yoo, Jina;Kang, Youn K.;Han, Su Jung;Lee, Chongmok;Lee, Bun Yeoul. And the article was included in Inorganic Chemistry in 2009.Name: 1-Chloro-4-iodobutane This article mentions the following:

Salen-type ligands comprised of ethylenediamine or 1,2-cyclohexenediamine, along with an salicylaldehyde bearing a Me substituent on its 3-position and a -[CR(CH2CH2CH2N+Bu3)2] (R=H or Me) on its 5-position, unexpectedly afford cobalt(III) complexes with uncoordinated imines. In these complexes, two salen-phenoxys and two 2,4-dinitrophenolates (DNPs), which counter the quaternary ammonium cations, coordinate persistently with cobalt, while two other DNPs are fluxional between a coordinated and an uncoordinated state in THF at room temperature The complexes of this binding mode show excellent activities in carbon dioxide/propylene oxide copolymerization (TOF, 8 300-13 000 h-1) but with some fluctuation in induction times (1-10 h), depending on how dry the system is. The induction time is shortened (<1.0 h) and activity is increased ∼1.5 times upon the replacement of the two fluxional DNPs with 2,4-dinitrophenol-2,4-dinitrophenolate homoconjugation ([DNP···H···DNP]–). Imposing steric congestion either by replacing the Me substituent on the salicylaldehyde with tert-Bu or by employing H2NCMe2CMe2NH2 instead of ethylenediamine or 1,2-cyclohexenediamine results in conventional imine-coordinating complexes, which show lower activities than uncoordinated imine complexes. In the experiment, the researchers used many compounds, for example, 1-Chloro-4-iodobutane (cas: 10297-05-9Name: 1-Chloro-4-iodobutane).
