metalation followed by concomitant intramolecular trans-insertion of C–C triple bond to aryl-Pd complex. The results were supported by various control experiments including with electron–deficient arenes and deuteriumlabeling studies. The deuteriumlabeling studies supports electrophilic palladation of aromatic C–H over activation of C–C triple bond of alkyne. The structure of synthesized compounds
