## Abstract The cyclization of differently substituted aryl alkynes with Pt^II^ or Au^I^ catalysts proceeds by __endo‐dig__ pathways. When Ag^I^ was used to generate reactive cationic Au^I^ catalysts, 2__H__‐chromenes dimerize to form cyclobutane derivatives by a Ag^I^‐catalyzed process. A DFT stud
