Acetylide complexes cluster chemistry

There has been a growing interest in the organometallic chemistry of allenyl-containing complexes. Although mononuclear propargyl complexes have proved to be versatile reagents in the synthesis of heterome-tallic allenyl clusters and nucleophilic attack of diazoalkanes at C carbon atoms of /u.2-i7, i7 -coordinated acetylides is an effective...
