摘要

trans-Alkenylalanes, readily obtainable via hydroaluminiation of acetylenes, react readily with aryl bromides and iodides in the presence of catalytic amounts of nickel complexes, such as tetrakis (triphenylphosphine)-nickel, to produce arylated alkenes in high yields, the stereochemistry of the products being> 99% trans.
