The first examples of CS induced PausonâKhand 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.
首次描述了由CS诱导的Pauson–Khand类型反应;2-烷基炔基苯异
硫氰酸酯在摩尔比为1的Mo(CO)6或Co2(CO)8的存在下,或在碳 monoxide气氛下使用催化量的Rh催化剂,转化为3取代的2H-
噻吩[2,3-b]
吲哚-2-酮。
