摘要

Abstract The air and water stable non-symmetrical pincer palladacycle [Me 2 NCH 2 (Cl) C= C (CH 2) 2 OP (i-Pr) 2-kNkCkP] PdCl 5, easily prepared from the chloropalladation of the hetero-substituted alkyne Me 2 NCH 2 C≡ C (CH 2) 2 OP (i-Pr) 2, is a highly efficient catalyst precursor for the coupling of aryl boronic acids and aryl chlorides. Both electron-rich and electron-poor aryl chlorides are efficiently coupled in the presence of 5 to furnish the ...
