摘要

Studies on the sp-sp intermolecular coupling reactions with the palladium water-soluble catalyst prepared in situ from palladium (I1) acetate and sulfonated triphenylphosphine P (C&bz-S03Na) 3 (TPPTS) in a homogeneous acetonitrile-water system, without Cu (1) promotor, afford diynes with moderate yields (45-65%). Under the same conditions, the sp2- sp coupling of 2-iodophenols or 2-iodoanilines and terminal alkynes followed by ...
