From Laboratory Curiosities to Industrial Applications: The World of Halogens

abstract:

Novel super acids offer the possibility of synthesizing hitherto unknown

compounds.[1] Based on such Lewis and Brønsted acids, we have

succeeded in synthesizing and characterizing so far unknown halonium

ions, which are ideal alkylation reagents due to their high reactivity.[2,3]

Furthermore it was shown, that e.g. chloronium ions can be stabilized by

polychloride monoanions such as [Cl3]-.[4]

Especially such polychloride anions offer new possibilities which are not

only of academic interest.[5-8] The value of trichlorides for chlorine

storage and chlorination reactions is only one aspect in this context.

Particularly, the inexpensive ionic liquid [NEt3Me][Cl3] shows a similar

and sometimes even advantageous reactivity compared to chlorine gas,

while offering a superior safety profile. Furthermore, this chemistry

shows also new applications in the direction of hydrochlorinations and

beyond.
