Abstract
Abstract The generation of (η 6-aryne) chromium complexes as reactive intermediates was investigated in two ways. Although earlier attempts directed towards triflate eliminations from a variety of tricarbonyl (phenyl triflate) chromium complexes had failed, more electron-rich phenyl triflate complexes were considered. This was accomplished either by substitution with two methoxy groups in the arene ligand or by replacement of one of the three ...
