Aldol Addition Reactions with Lithium & Proline (IOC 21)

*Disclaimer* LDA can also afford E-enolates, and usually a mixture is obtained; if an ester or an amide is used instead of a ketone, the selectivity can change! Depending on the ketone that is used, the selectivity can also reverse. --------------------------------------------------------

Synthesis of a Bromoalkane (n-Bromopropane)

In this video, I will be making n-bromopropane by brominating 1-propanol. The n-bromopropane can then be used in a Grignard reaction to make butyric acid (smell of vomit). Here is the video of me using it in a Grignard reaction: http://youtu.be/_wmx65zQk58 This process can be used as a
