An analysis of 17 O carbonyl chemical shifts of 50 substituted benzaldehydes leads to an empirical equation, δ cal ( 17 O) = 564.0 + ΣΔ o + ΣΔ m + ΣΔ p + C , for calculating 17 O chemical shifts. This equation is based on a linear regression analysis using 11 substituent parameters and leads to good conformity with the expected data. Copyright © 2004 John Wiley & Sons, Ltd.
