Reaction #1: Synthesizing alkynes by double dehydrohalogenation
-Turns Alkane with two halogen leaving groups into a alkyne using strong base (NH2)
Note: Nasiri does not use "mineral oil" in her dehalogenations.
For the second reaction (geminal dihalide), rather than using excess NaNH2 and heat, Nasiri writes two steps: 1.) 3 equivalents of NaNH2 2.) H2O
Reaction #2: Reduction of alkynes by catalytic hydrogenation
-Turns Alkyne into either an alkane, cis alkene, or trans alkene (depending on reagent)
Note: we can form a Grignard's reagent or Cuprate reagent from a haloalkene
Reaction #5: Addition of OH to alkyne
First Video = Markovnikov addition of OH and Acid-catalyzed tautomerization
Second Video = Anti-Markovnikov addition of OH and base-catalyzed tautomerization
