Reactions of Nucleophiles with sp Hybridised Carbon Centres

Alternatively, the metal may act by assisting the departure of a leaving group from the intermediates generated in Fig. 4-4, as is shown in Fig. 4-5. 

We shall start our study by considering reactions involving attack of nucleophiles upon unsaturated centres within ligands co-ordinated to a metal. 

2 Reactions of Nucleophiles with sp Hybridised Carbon Centres 

In this book we are not concerned with organometallic reactivity of compounds containing M-C bonds, and so to all intents and purposes this section is about the reactions of nitriles or cyanides with nucleophiles. Reactions of co-ordinated alkynes are adequately discussed elsewhere.
