involving a phosphinoauration and a gold‐catalyzed 6‐endo‐digcyclization step, was developed. Starting from modular and simple‐to‐prepare phosphadiynes, π‐extended phosphoniumfluorenes were synthesized. The mechanistic proposal was supported by kinetic measurements and by the trapping of key intermediates. These led to important conclusions for the gold‐catalyzedhydroarylation mechanism.
