摘要

Abstract: Friedel-Crafts acetylation of diarylacetylenedicobalt hexacarbonyl proceeds readily and in high yield. Introduction of the first acetyl substituent is a very rapid process, but the second acetyl group is introduced more slowly. In all cases, para substitution was observed, presumably because of steric factors. Deactivation of aluminum chloride by its coordination at the newly formed ketone function caused some difficulties in some cases. Competition ...
