A Lewis acid catalyst facilitates the reaction and both aluminium(III) chloride and titanium(IV) chloride have been used. An example of the effect of a catalyst is shown in Scheme 6. Chlorination of carbonyl diisothiocyanate (6) in the absence of a catalyst gave the carbonimidic dichloride ...
The diiodine basicity (a soft Lewis basicity) of pyrazoles and indazole was measured by means of the formation constant of the diiodine–azole complexes in heptane at 298 K <1997JPO669>. The preferred sites of diiodine fixation were the N-2 nitrogens in pyrazoles and indazole. The double...
The iodinemoleculecan act as a Lewis acid in that it combines with various Lewis bases. The interaction is weak, however, and few solid complex compounds have been isolated. The complexes are easily detected in solution and are referred to as charge-transfer complexes. Iodine, for example, is...
In terms of structure and/or bond types, explain why iodine solid (I2) is easier to break than solid sodium chloride, NaCl. Intermolecular force of attraction Covalent molecules have vander waal forces of attraction, or hydrogen bonding, as the ...

Structure of iodine pentoxide Iodine oxides are the most stable of all the halogen oxides, because of the strong I–O bonds resulting from the large electronegativity difference between iodine and oxygen, and they have been known for the longest time.[25] The stable, white, hygroscopic iodine ...
ChlorideIonic liquidCrystal structureThe interhalides [PCl4](2)[ICl2][ICl4] (1) and [BnMe3N](2)[I2Cl3][ICl4] (2) were prepared by halogen exchange reaction of the interhalogen ICl3 or [BnMe3N][ICl4] (Bn: benzyl) with the strong Lewis acid PBr5 and the soft Lewis acid BiBr3...
The iodine can form CTCs with conjugated organic molecules (Lewis base), signifying the electrical conductivity of I2@COFs can be further improved. And these conjugated structures affect the uptake of iodine. For example, COF-LZU1 with a π-π conjugated structure exhibited much higher iodine ...
