Kinetic Study of Charge Transfer Complexes of Iodine With Some Crown Ethers in Nonaqueous Solvents

“…3 show the absorbance-time curves DB24C8.I 2 and B18C6.I 2 complexes in chloroform , dichloromethane and 1,2-dichloroethane solution. The above experimental observations seem to be in accord with the following mechanism, which has been proposed before [9][10][11][12][13]. The proposed mechanism for formation of the charge transfer complex as presented at the following:…”

“…The stability of these complexes appears to be related to the macrocycles , cavity sizes; It is at maximum when the cavity diameter matches the ionic size [8]. During the past two decades, a growing interest has been focused on the complexing ability of these macrocyclic ligands as electron-pair molecules towards neutral and, especially, molecular iodine [9][10][11][12][13]. Iodine has been found to form with many compounds charge transfer complexes whose properties have been thoroughly studied [14][15][16][17][18].…”

Compounds of Complex Halo and Pseudohalo Acids of the Group IIB Metals, Part V [1] Preparative and Spectroscopic Studies of the [Hg2I5]-, [Hg2I6]2- and [Hg3I8]2- Ions

“…The ca. 360 nm maximum is assigned to the 7ig -» eru* transition of the I3-ion [13]. The spectra of the quinolinium complexes show absorption maxima at 223,226, 231, 271, 276, 282, 287, 293, 300, 305 and 313 nm; these are due to electronic transitions of quinoline, since they appear in the spectra of Qu and QuHI.…”

Compounds of Complex Halo and Pseudohalo Acids of the Group II B Metals, Part HI [1]Spectral Studies of the Hgl- 3 Ion

“…Very recent experiments in our laboratory have shown, that the 350 nm maximum in the UV spectrum of HHgl^An is due to the ng -> cru* transition of the I3 ion [15]. …”
