Abstract Reaction of aryl iodides with 1,2-disubstituted aryl alkenes in the presence of TBABr/TBACl gave high yields of the Mizoroki–Heck product. Phosphine ligands were used for the modulation of reactivity and stereoselectivity, for the reaction of 4-iodoanisole with cinnamaldehyde. tert-Bu3P.HBF4 gave the highest E:Z ratio of 1:0.08. The use of PEG-200 and PEG-400 as solvent could activate the
摘要 在 TBABr/TBACl 存在下,芳基碘化物与 1,2-二取代芳基烯烃反应得到高产率的 Mizoroki-Heck 产物。膦配体用于调节反应性和立体选择性,用于 4-碘苯甲醚与肉桂醛的反应。tert-Bu3P.HBF4 的 E:Z 比最高,为 1:0.08。使用 PEG-200 和 PEG-400 作为溶剂可以激活芳基碘化物与各种 1,2-二取代芳基烯烃的反应。图形概要
