    • We also examined an ETPO-type ligand bearing such a substituent as H, Me, Ph or t-Bu at its 4-position, however, none of them improved the yield and selectivity of 3a.

    • Although we also conducted the reactions of 3-methyl or 4-methoxybenzyne to investigate the regioselectivity in detail, both reactions resulted in the formation of a complex mixture.
