Abstract

The first examples of CS induced Pauson–Khand type reactions are described; 2- alkynylphenyl isothiocyanates were converted to 3-substituted-2H-thieno [2, 3-b] indol-2- ones in the presence of a stoichiometric amount of Mo (CO) 6 or Co2 (CO) 8, or a catalytic amount of Rh catalyst under an atmospheric pressure of carbon monoxide.
