AI Article Synopsis

  • Researchers tested various combinations of five different catalyst precursors and 13 phosphorus ligands.
  • The goal was to find catalysts that promote carbocyclization-trapping reactions using N-hydroxyphthalimide.
  • The study found specific catalysts that preferentially support this desired reaction pathway over cycloisomerization.

Article Abstract

[reaction: see text] Screening combinations of five catalyst precursors with 13 phosphorus ligands identified cyclization catalysts that favor carbocyclization-trapping with N-hydroxyphthalimide over a competing cycloisomerization mode.
