The economic amide base lithium dicyclohexylamide (Cy2NLi) undergoes fast (40 s) and convenient (0 °C) in situ trapping flow metalations of a broad range of functionalized aromatics in the presence of various metal salts. The economic amide base lithium dicyclohexylamide (Cy2NLi) allows fast and convenient (40 s, 0 °C) in situ trapping flow metalations of a broad range of functionalized arenes, heteroarenes and acrylate derivatives in the presence of various metal salts (ZnCl2·2LiCl, MgCl2, LaCl3·2LiCl). The resulting Zn-, Mg- or La-organometallic intermediates are trapped with various electrophiles in high yields. These flow metalations are easily scaled-up without further optimization.
