Abstract: The intramolecular hydrogen-bonding and keto-enol tautomerism of a series of 1-aryl-3-tolyl-1,3-propanediones were studied by 1H NMR. Both δOHand lgK(K=[enol]/[keto]) can be correlated with substituent constants satisfactorily. +1 and +Rsubstituents enhance the hydrogenbond-ing and decrease the content of enol form.
Key words: β-Dlketone, Hydrogen-bonding, Keto-enol tautomerism
