Abstract
| - This paper describes highly efficient allyl cross-coupling reactions of allylindiums with organic electrophilessuch as aryl and vinyl triflates, vinyl halides, dibromoolefin,and alkynyl iodide. The reactions were carried out using 4mol % Pd(PPh3)4 in the presence of 3 equiv of LiCl in DMFat 100 °C under a nitrogen atmosphere. Allylindium, generated from the reaction of 1 equiv of indium with 1.5 equivof allyl halide, gave the best result as a coupling partner.The present method is mild and simple to apply, and itproduces a diverse range of allylic compounds in good toexcellent yields.
