Substitution of carbon monoxide ligands by one acetylene is the first step in the reaction of alkynes with metal carbonyls. This is well-established in the case of cobalt carbonyls by the isolation of substitution-type complexes of formula RC2R’Co2(CO)6 (1) and RC2R′Co4(CO)10 (2). Three different types of alkyne-substituted iron carbonyls have been isolated from iron carbonyls particularly with acetylenes having bulky substituents (3). They have recently been shown to be intermediates in the formation of complexes with more complicated organic ligands as well as of cyclic organic products.
