摘要

Abstract The palladacycle [Pd (k 2-C, NC [DOUBLE BOND](C 6 H 5) C (Cl) CH 2 NMe 2)(μ- Cl)] 2 (1) derived from the chloropalladation of 3-(dimethylamino)-1-phenyl-1-propyne and its phosphine adduct [Pd (k 2-C, NC [DOUBLE BOND](C 6 H 5) C (Cl) CH 2 NMe 2) P (4-CF 3 C 6 H 4) 3 (Cl)](3) promote the alkynylation of bromo-and iodoarenes under relatively mild reaction conditions. The coupling of iodoarenes and activated bromoarenes with terminal ...
