An efficient nickel-catalyzed reaction for the phosphination of vinyl bromides and chlorides was developed. The procedure uses a combination of up to 1 mol% of nickel acetylacetonate, triethylamine and dimethylformamide as a solvent. The double bond geometry of the vinyl halides was retained under the reaction conditions.
开发了一种高效的镍催化反应,用于乙烯基溴和氯的膦化。该方法使用高达1摩尔百分比的乙酰丙酮镍、三乙胺和二甲基甲酰胺作为溶剂。在反应条件下,乙烯基卤的双键几何结构保持不变。
