Abstract

Phosphorus oxyacids are converted to their halogenated analogues under mild conditions. α-Haloenamines are shown to be effective halogen transfer reagents affording good to high yields of the desired products at reaction times, in some cases, less than one minute.

Key words

phosphorus - α-haloenamines - halogenation - fluorine - chlorine
