Enolates can act as a nucleophile in S N 2 type reactions. Overall an α hydrogen is replaced with an alkyl group. This reaction is one of the more important for enolates because a carbon-carbon bond is formed. These alkylations are affected by the same limitations as S N 2 reactions previously discussed. barmer map

"WebJun 20, 2024 · In our preliminary study, non-activated phenyl tosylate and diisopropyl phosphite were selected as the common substrates (Table 1 ). Use of a proper phosphine ligand was crucial for this reaction. A series of ligands was evaluated for their efficiency in this C–P bond coupling process. The reaction did not proceed without a ligand. " - Phenyl tosylate
