gamma-Selective Cross-coupling of Potassium Allyltrifluoroborates with Aryl and 1-Alkenyl Bromides Catalyzed by a Pd(OAc)_2/D-t-BPF Complex

摘要

Cross-coupling reactions of [RCH=CHCH_2BF_3]K with aryl or 1 -alkenyl bromides occurred at the gamma-carbon of an allylborane moiety with perfect regioselectivities (>99%) in the presence of a palladium/D-t-BPF complex and K_2CO_3 in refluxing THF.
