This report describes the Pd(0)-catalyzed fluorination of linear allylic chlorides and bromides, yielding branched allylic fluorides in high selectivity. Many of the significant synthetic limitations previously associated with the preparation of these products are overcome by this catalytic method. We also demonstrate that a chiral bisphosphine-ligated palladium catalyst enables highly enantioselective
本报告描述了 Pd(0) 催化的线性烯丙基氯化物和溴化物的氟化,以高选择性产生支化的烯丙基氟化物。这种催化方法克服了以前与这些产品的制备相关的许多重要的合成限制。我们还证明了手性双膦连接的钯催化剂能够高度对映选择性地获得一类支链烯丙基氟化物,这些氟化物可以很容易地多样化为有价值的氟化产品。
