The reactivity of alkynes with the imido clusters Ru{sub 3}({mu}{sub 3}-NPh){sub 2}(CO){sub 9}, H{sub 2}Ru{sub 3}({mu}{sub 3}-NPh)(CO){sub 9}, Fe{sub 3}({mu}{sub 3}-NPh)(CO){sub 10}, Fe{sub 3}({mu}{sub 3}-NPh){sub 2}(CO){sub 9}, and H{sub 2}Fe{sub e}({mu}{sub 3}-NPh)(CO){sub 9} has been examined. The cluster Fe{sub 3}({mu}{sub 3}-NPh)(CO){sub 10} reacts regiospecifically with a series of alkynes to form the binuclear ferrapyrrolinone complexes Fe{sub 2}({mu}{sub 2}-{eta}{sup 3}-RC{double bond}C(R{prime})C(O)NPh)(CO){sub 6}, possessing a metallacycle formed by coupling of the alkyne with CO and the imido ligand. The bis(imido) cluster Ru{sub 3}({mu}{sub 3}-NPh){sub 2}(CO){sub 9} reacts with PhC{triple bond}CPh to form the tetranuclear cluster Ru{sub 4}({mu}{sub 3}-NPh){sub 2}({eta}{sup 2}-{mu}{sub 2}-PhC{triple bond}CPh)(CO){sub 10}, which has been crystallographically shown to possess a butterfly arrangement of the four ruthenium atoms with the alkyne bridging the hinge of the butterfly in a perpendicular fashion and with the imido ligands bridging the open triangular faces of the butterfly.
