Carbozincations constitute undoubtedly one of the most fascinating fields of organozinc chemistry. Whereas alkenes and alkynes are not traditionally considered as electrophiles in polar organometallic chemistry, carbometallation reactions offer many synthetically... 

The structures of platinum(O) complexes of alkynes are fully summarized in Chapter 39 of Comprehensive Organometallic Chemistry and need not be covered here. 

Contrary to the rich organometallic chemistry of cyclopropylacetylenes with main group elements, tr-bonded transition metal complexes of the alkynes are rare. Nevertheless, the single example given in the literature is of a stable crystalline compound, which permits insight into the structure of cyclopropylethynyl complexes in the solid state. 

The oligomerization, cooligomerization and metathesis of small alkenes and alkynes and much of cobalt-catalyzed hydroformylation fall within the scope of the companion work Comprehensive Organometallic Chemistry and are not dealt with here.

Similar to the abovementioned silver nhc coordination compounds, carbene chemistry has also been dominant in the field of gold organometallic chemistry. Noteworthy examples include a Au(PPh3)-compound derived from tetraaminoallene, that can be rationalised in terms of a dicarbene with ylide character and which, owing to the electron-rich character of the central carbon atom, offers the potential for dimetallation products.108 Non-activated allenes and alkynes have been found by Lavallo to be readily aminated by cationic carbene gold complexes.109 For this purpose, a 2,6-diisopropylphenyl functionalized cyclic alkylaminocarbene gold(I) complex...

Within this class of compounds the reactivity of the M2(OR)6 compounds is particularly noteworthy. These have been shown to be templates for organometallic chemistry by the addition of unsaturated molecules such as CO, alkynes, ethene, allene, 1,3-dienes, a,/3-unsaturated ketones, etc.117 Some reactivity unique to di-... 

This article is concerned with one specific aspect of cluster organometallic chemistry, and describes the synthesis, characterization, structure, and reactivity of transition metal clusters containing alkyne, or alkyne-derived ligands. Alkynes display a diverse reactivity in their reactions with carbonyl clusters, and exhibit a wider range of coordination modes than any other simple, unsaturated molecule. It is this compelling diversity that has prompted the authors to undertake this review. 

Some of the most prolific reactants in organometallic chemistry are alkynes." At some time or the other every new cluster is reacted with an aUcyne. Not surprisingly, alkyne complexes dominate the C2-containing clusters. Alkynes most commonly bridge the triangular face of the cluster, either as (18) or as (19) ligands. In tetrametallic and...
