Pyridinium Dichlorobromate: A New Stable Brominating Agent for Aromatic Compounds
Synthesis, 2004Pyridinium dichlorobromate (PyHBrCl 2 , 1) is a new example of iminium-trihalide complexes. The compound is prepared from pyridine and chlorine in the presence of aqueous hydrogen bromide. The crystalline trihalide is quite stable and acts as a safe source of positive bromine.

Three new compounds of the benzoyl-pyridinium type were prepared: 1-phenacyl-2-methylpyridinium chloride (1), 1-benzoylethyl-pyridinium chloride (2) and 1-benzoylethylpyridinium-4-aldoxime chloride (3) and assayed in vitro for their inhibitory effect on human blood acetylcholinesterase (AChE).

Organophosphorus compounds (OP) used as pesticides or warfare nerve agents are strong poisons. They inhibit acetylcholinesterase (AChE) by phosphylating its catalytic site. Substrates and reversible ligands can protect cholinesterases from phosphylation. On the other hand some compounds, due to their structure (mostly oximes) protect the enzyme as well
