procedure for the palladium-catalysed Suzuki–Miyaura coupling of various alkenyl tosylates with alkenyl MIDA boronates has been developed. Commercially available trans-bromo[N-succinimidyl-bis(triphenylphosphine)]palladium(II) [Pd(PPh3)2NBS] is an effective catalyst under the slow release conditions of MIDA boronates; with less activated alkenyl tosylates addition of the cheap, air-stable tricyclohexylphosphine
已经开发了一种实用的程序,用于各种链烯基甲苯磺酸盐与链烯基MIDA硼酸酯的钯催化的Suzuki-Miyaura偶联反应。在MIDA硼酸盐的缓释条件下,市售的反式-溴[ N-琥珀酰亚胺基双(三苯基膦)]钯(II)[Pd(PPh 3)2 NBS]是有效的催化剂。活化的烯基甲苯磺酸盐含量较低时,添加廉价的,空气稳定的三环己基膦四氟硼酸酯可提高反应活性。
