1. Introduction to the Alkyne Triple Bond.

2. The Titano-hydrogenation of Alkyne hydrocarbons was studied by the method of G. C. track.

3. The situation of the improving hydrogenation catalyst for alkyne series in recent over 10 years in France petroleum institute was summarized.

4. A new test method, in which alkyne impurity content in 1,3-Butadiene is determined by a capillary gas chromatograph, was introduced.

5. Alkyne complexes, especially its terminal hydrogen, is not only presence weak acidity but also has reaction activation.

6. The nucleophiles include alkene, alkyne, alcohol, acid, amine, water, etc.

7. Acetylene (ethyne)Simplest alkyne, C2H2. A colourless, flammable, explosive gas, it is used as a fuel in welding and cutting metals and as a raw material for many organic compounds and plastics.

8. This type of reaction has signicant advantages, the alkyne proceeds the coupling reaction with the halogen atom as the leaving group.

9. The recent development about applications of ionic liquids(ILs) to transition metal -catalyzed cyclization of alkyne and enyne compounds was introduced.

10. This paper reports the route of synthesis multisubstituted alkenes by addition reaction of alkyne zirconalkylation with zirconocene complexes.

11. This part mainly focused on the synthesis of propargylic alcohols in many methods including metal acetylides, terminal alkyne derivatives and the direct alkynyl C-H activation.

11. try its best to gather and make good sentences.

12. The computation indicated that the stable silicyl alkene is produced by the addition reaction of silicon alkyne and hydro-gen.

13. In Chapter III, we have developed the Ag-catalyzed intramolecular organic azide and alkyne cyclization to synthesize of 1,3-disubstituted isoquinolines or non-substituted isoquinolines.
