reaction aimed at identifying active palladium complexes have revealed a new species that is formed in situ. This complex has been identified as the palladium iodide dimer, [(JessePhos)PdI2]2, which has been found to be a competent single-component precatalyst for the silyl-Heck reaction. This complex is easily prepared and is temperature, moisture, and air stable. Additionally, this precatalyst provides
旨在鉴定活性钯配合物的甲硅烷基-Heck反应的研究揭示了一种原位形成的新物种。该络合物已被鉴定为碘化钯二聚体[(JessePhos)PdI 2 ] 2,已发现它是甲硅烷基-Heck反应的有效单组分预催化剂。该配合物易于制备,并且对温度,湿度和空气稳定。另外,与以前的系统相比,这种预催化剂具有更高的活性和更高的重现性。
