(Chemical Equation Presented) A new method has been developed for in situ halogenation of acidic sp2 carbon-hydrogen bonds in heterocycles and electron-deficient arenes. Either selective monohalogenation or one-step exhaustive polyhalogenation is possible for substrates possessing several C-H bonds that are flanked by electron-withdrawing groups. For the most acidic arenes, such as pentafluorobenzene, K3PO4 base can be employed instead of BuLi for metalation/halogenation sequences.

Besides the formation of acylium ions, the molecular ions of 1-acyl-1,2,4-triazoles substituted (R) at position 3 lose competitively ketene and carbon monoxide after electron impact ionization, but the ketene loss dominates largely if R is a strong electr
