WebAcyloin Condensation. The bimolecular reductive coupling of carboxylic esters by reaction with metallic sodium in an inert solvent under reflux gives an α-hydroxyketone, which is known as an acyloin. This reaction is favoured when R is an alkyl. With longer alkyl chains, higher boiling solvents can be used. The intramolecular version of this ...
WebThe two-step mechanism below has been proposed for a reaction between nitrogen monoxide and molecular chlorine: Step 1: NO ( g) + Cl 2 ( g) ⇌ NOCl 2 ( g) fast Step 2: NOCl 2 ( g) + NO ( g) 2NOCl ( g) slow. Use this mechanism to derive the equation and predicted rate law for the overall reaction.
