The reaction of α-halosubstituted β-ethoxyvinyl trifluomethyl ketones with 2-aminopyridine gives 3-trifluoroacetyl imidazo [1,2-a]pyridine and 3-halo-1,1,1,-trifluoro-4-(2-pyridinylamino)-3-buten-2-ones. The product ratio depends on the nature of the α-halogen atom and the solvent.

The synthesis of new 3-chlorodifluoroacetylated imidazo[1,2-a]pyridines 1-6 and their difluoroacetyl derivatives is presented. The reductive cleavage of the halogenated ketones was investigated by cyclic voltammetry, and tetrakis(dimethylamino)ethylene (T
Tetrakis(dimethylamino)ethylene (TDAE) as a useful reductant of some chlorodifluoromethylated ketones. A new approach for the synthesis of α,α- difluoroketone derivatives

Tetrakis(dimethylamino)ethylene (TDAE) was found to be an effective reductant of chlorodifluoromethylated ketones 1-3. The generated α,α- difluoroacetyl anion was trapped with several aldehydes 4-7, under mild conditions, to give the corresponding 2,2-difluoro-3-hydroxy ketone derivatives 8-13, in moderate yields.
