title: Controlling mode selectivity in palladium-catalyzed bisdiene carbocyclizations: optimizing for cyclization-trapping over cycloisomerization.
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.
