Key Reactions and Mechanisms in Organic Chemistry

These flashcards contain key vocabulary and definitions related to the reactions and mechanisms covered in the organic chemistry lecture.

Halogenation of Alkynes

Alkynes undergo halogenation through reactions with HCl (with/without water) or Br2/Cl2, leading to alkyl halides or vicinal dihalides.

Markovnikov's Rule alkynes

During hydration reactions of alkynes, the OH group attaches to the more substituted carbon.

Oxymercuration-Demercuration alkynes

Uses mercury reagents to prevent rearrangements in hydration reactions, producing stable alcohols.

Alkyne Reduction

Alkynes can be reduced to alkenes using H2 with Pd/C or by dissolving metals like Na or Li in ammonia.

Formation of Alcohols from Alkynes

Hydroboration followed by oxidation can produce primary or secondary alcohols from alkynes.

Acetylide Anion Synthesis

Using alkaline metals, terminal alkynes can create strong nucleophiles for carbon chain elongation.

Tautomerization

The conversion of an enol to a keto form, an important process in organic transformations.
