Abstract:
For the first time, the existence of a strong intramolecular 1,4-interaction between the phosphorus atom and the oxygen atom in alpha-keto-stabilized ylides has been demonstrated by means of theoretical calculations. This interaction has a notable influence on the conformational preferences and rotational barriers of alpha-stabilized phosphorus ylides and bis-ylides.
