Iridium‐Catalyzed Addition Reactions of Ethynylsilane to Quinolines and Isoquinolines Activated by Acyl Chloride.

Addition reactions of ethynyltrimethylsilane to various quinolines and isoquinolines activated by acyl chloride are catalyzed with a few Ir-complexes to afford 2-trimethylsilyl-ethynyl-1,2-dihydroquinolines and 1-trimethylsilylethynyl-1,2-dihydroisoquinolines in good to high yields.
