摘要

We have conceptualized1 the view that in reactions of substituted cyclohexanones with nucleophiles there is first a complexation of the carbonyl oxygen with the nucleophile's cation component and that the resulting changes in the torsion angles about the carbonyl carbon must depend on the nature, location, and orientation of a ring substituent. An increase in the torsion angles of the carbonyl oxygen with the ring positions 3 and 5 on the ...
