Halogens interhalogens

In a series of seven recent publications, these Italian authors21-27 reported isobutylene homo- and copolymerizations using alkylaluminum coinitiators in the presence of halogen, interhalogen compounds and alkyl halide initiators. The following conclusions21 are reported in the first paper.

As a final example of this section, we cite Benson and Haugen s (1965) electrostatic model for the prediction of activation energies for four-center gas phase reactions. Of interest here are the additions of hydrogen, halogens, interhalogens and hydrogen halides to alkenes. To obtain the calculated value of the activation energy for the addition reaction (196),... 

The presence of the potassium atoms causes the distance between the layers of carbon atoms to increase from the value of 235 pm in graphite to 540 pm in C8K. When rubidium and cesium atoms are placed between the layers, the distances between the carbon layers are 561 and 595 pm, respectively. As would be expected for materials that contain atoms of an alkali metal, these materials are extremely reactive in air, and they react explosively with water. A large number of other intercalation compounds have been prepared that have halogens, interhalogens, or metal halides as the included substances.
