Document Summary

Given the presence of pi bonds, alkynes are similar to alkenes in their ability to act as a nucleophile. Many of the addition reactions of alkenes also work on alkynes. It is used in blow torches and as a precursor for the synthesis of more complex alkynes. More than 1000 different alkyne natural products have been isolated. An example of a synthetic alkyne is ethynylestradiol. Ethynylestradiol is the active ingredient in many birth control pills. Alkynes are named using the same procedure we used in chapter 4 to name alkanes with minor modifications: identify the parent chain, which should include the c c triple bond, identify and name the substituents. Alkynes are named using the same procedure we used in chapter 4 to name alkanes with minor modifications: assign a locant (and prefix if necessary) to each substituent giving the c c triple bond the lowest number possible.
