Abstract	Compounds with M—C(sp2) or N—C(sp) bonds show a reactivity different from that of metal—alkyl complexes. This paper describes some reactions of transition metal acetylides, which are characterised by electrophilic additions to the s—carbon. Cycloaddition to olef ins has given cyclobutenyl, butadienyl and allylic derivatives, while reactions with tropylium and arenediazonium salts generate new types of vinylidene complex. Unusual halogen—substituted vinylidene ligands are formed by direct addition of Cl2, Br2 or 12 to metal acetylides. Subsequent reactions of these complexes are discussed. The conversion of cluster— bound acetylides to vinylidenes is described, and the mild reduction of an acetylide to carbon and methyl on an open Ru5 cluster is an interesting example of the modification of reaction pathways of small molecules by metal clusters.
