CSe and CS couplingreactions. The performance of these complexes for CSe reactions was investigated in chalcogenoacetylene synthesis. The reactions were carried out under mild and aerobic conditions and afforded selanylalkynes bearing a variety of electron-withdrawing and electron-donating groups. The performance of these catalysts for CS coupling was investigated through the reaction of aryl halides
