This chapter focuses on the differences between alkynes and alkenes, particularly those that affect synthetic work. It explains that one difference concerns the CC double bond, which is usually created from saturated intermediates by elimination but is formed in a different way in alkynes.

Tremendous advances in the field of alkyne metathesis have been recorded over the last decade. The development of molybdenum alkylidyne complexes endowed with silanolate ligands allowed several problems of traditional alkyne metathesis to be solved at once.

This chapter talks about the high-s character of an sp hybridized carbon atom, which meant that an acetylene anion is stabilized, and the deprotonation of acetylenes, which is possible with a wide range of strong bases. It emphasizes the careful control of conditions of a strong base in the deprotonation of an acetylene to avoid side reactions ...

This chapter examines alkyne complexes. Alkynes (acetylenes) form complexes with transition metals in a similar way to alkenes, and similar bonding schemes can be applied. However, there are characteristic differences in the bonding of alkynes to metals compared to alkenes.
