English term
giving the product in 97% in enantiomeric excess
English
Science
Chemistry; Chem Sci/Eng
The text is a patent application on an enantiomeric synthesis method.
"The reaction proceeds within 5 minutes giving the (R)-alcohol in 97% in enantiomeric excess."
Would you say that the figure 97% refers to the total yield or to the enantiomeric excess?
"The reaction proceeds within 5 minutes giving the (R)-alcohol in 97% in enantiomeric excess."
Would you say that the figure 97% refers to the total yield or to the enantiomeric excess?

in 97% enantiomeric excess
Althiugh the phraee has an error, I would say they are referring to the level of enantimeric excess, not the overall yield.

Therefore the percentage term refers to the enantiomeric excess (97% - R) and not rhe yield of the racemic mixture.
