CHM247H1 Chapter Notes - Chapter 9: Nucleophile, Lindlar Catalyst, Quinolone
Document Summary
Chapter 9: alkynes: an introduction to organic synthesis. Alkenes what reactions did they undergo: halogenation (x2, hydrogenation (h2, hydration (h2o, halohydrogenation (hx, halohydrin formation (x, oh, oxidation. Use suffix yne , start numbering at end nearest c c. Compounds with double & triple bonds are enynes . Numbering of enyne starts from end nearest multiple bond (either one) 9. 2 preparation of alkynes: elimination reactions of dihalides. [nanh2 = sodamide (sodium amide) an extremely strong base] Jasmyn lee: similar to alkene reactivity; h2o addition can go. Tautomers constitutional isomers; two isomers that under spontaneous interconversion accompanied by the change in position of a h: tautomers differ in the position of a double bond and a. Hydrogen atom: tautomers are in equilibrium with each other. Hydration of an internal alkyne results in a mixture of ketones. A similar reaction occurs with alkynes, but a hindered dialkyl borane is used to prevent addition of two diborane molecules.
