Vinyl nosylates derived from 1,3-dicarbonyl compounds could be engaged in Suzuki–Myaura cross coupling reactions with aryl-, vinyl- and methylboronic acids or trifluoborate derivatives at room temperature in the presence of 2 mol% of [1,1′-bis(diphenylphosphino)ferrocene]dichloropalladium(II) [PdCl2(dppf)]. One-pot procedures have been set up for practical and efficient nosylation–cross-coupling reactions
在室温下,在存在2 mol%[1,1'-bis]的情况下,可以将衍生自1,3-二羰基化合物的乙烯基Nosylates与芳基,乙烯基和甲基硼酸或三氟硼酸酯衍生物进行Suzuki-Myaura交叉偶联反应(二苯基膦基)二茂铁]二氯钯(II)[PdCl 2(dppf)]。已经建立了一锅法,以进行实用,有效的烷基化-交叉偶联反应。作为便宜的新型假卤化物,壬基磺酸盐可提供非常稳定的化合物,并且在Suzuki-Myaura交叉偶联反应中非常有效(21个实例,占44-99%)。
