This paper describes highly efficient allyl cross-coupling reactions of allylindiums with organic electrophiles such as aryl and vinyl triflates, vinyl halides, dibromoolefin, and alkynyl iodide. The reactions were carried out using 4 mol % Pd(PPh3)4 in the presence of 3 equiv of LiCl in DMF at 100 degrees C under a nitrogen atmosphere. Allylindium, generated from the reaction of 1 equiv of indium
本文描述了烯丙基lin与有机亲电子试剂(例如芳基和乙烯基三氟甲磺酸酯,乙烯基卤化物,二溴代烯烃和炔基碘)的高效烯丙基交叉偶联反应。在3当量的LiCl存在下,在DMF中,在氮气气氛下,在100℃下,使用4mol%的Pd(PPh 3)4进行反应。由1当量的铟与1.5当量的烯丙基卤反应生成的烯丙基铝作为偶合伴侣可提供最佳结果。本方法温和且易于应用,并且以良好至优异的产率产生了多种烯丙基化合物。
