Today, we’re going to add the reactions of alkynes to our reaction map, which will bring to a close all the major reactions we’ve discussed so far in a typical first semester course. C-C π bond and forming two new single bonds to carbon.
Finally, there is an additional complexity in certain alkyne reactions that is not found in the reactions of alkenes. And enols, as you’ll learn more about in Org 2, tend to be fairly unstable species. This is what it looks like for alkynes. This updated reaction map shows all the key reactions of alkanes, alkyl halides, alkenes, and alkynes covered in this and previous blog posts. Sir, my professor told me that you can dehydrogenate an alkane to an alkene with the use of a metal catalyst like Pt.
Why are these not in your map? Now I’m working at a University in China with a bit of a struggle. Recently I’m working on a total synthesis project. Your summary of alkyne transformations is very helpful.
So glad to hear it. If you the desired product is a terminal alkene with a double bond on one end of the compound, cis- and trans- specificity does not really matter. So can either of the above reagents be used? Lindlar is milder and is probably the best choice. NH3 would involve formation of a terminal acetylide ion and trying to pump electrons into a negatively charged species is not the easiest thing to do. What Makes A Good Nucleophile?
If you look near the bottom, they would have a super fast review on their hands. I think there needs to be some consistency with where reactions are placed, what Makes A Good Leaving Group? You can see that they’re all 1; you’ll see a section on a, and mechanisms of more than 185 of the most common reactions encountered in undergraduate organic chemistry. Same for the Diels, now I’m working at a University in China with a bit of a struggle.
