and their difluoroacetyl derivatives is presented. The reductive cleavage of the halogenated ketones was investigated by cyclic voltammetry, and tetrakis(dimethylamino)ethylene (TDAE) was found to be an effective reductant for the generation of the corresponding α,α-difluoroacetyl anions and for the synthesis of new gem-difluoromethylated imidazo[1,2-a]pyridine derivatives 7–12.
新的3 chlorodifluoroacetylated合成咪唑并[1,2一]吡啶1 - 6和它们的二氟乙酰基衍生物被呈现。通过循环伏安法研究了卤代酮的还原裂解,发现四(二甲基氨基)乙烯(TDAE)是有效的还原剂,用于生成相应的α,α-二氟乙酰基阴离子和合成新的宝石-二氟甲基化咪唑并[1,2一]吡啶衍生物7 - 12。
