For the Rh(I)-catalyzed denitrogenative transannulation of 1,2,3-thiadiazoles with alkynes, the effect of the coupling partner (alkyne, alkene or nitrile), 1,2,3-thiadiazole substituent and ligand on regioselectivity has been previously reported. However, the role of the alkyne substituent has not been examined. This work reports systematic computational and experimental studies addressing how the
