摘要

Sodium 2-(prop-2′-ynyloxy) benzoate 1a reacted with the aryl iodides 2–10 in the presence of bis (triphenylphosphine) palladium (II) chloride, cuprous iodide and triethylamine in CH3CN–DMF to yield the disubstituted alkynes 11–19 in good yields (48– 58%). Similarly, sodium 2-[N-benzyl-N-(prop-2′-ynyl)] aminobenzoate 1b on reaction with aryl iodides under palladium–copper catalysis afforded the disubstituted alkynes 20–22. ...
