摘要：

C-13- and H-1-n.m.r.-data of substituted beta-diketones and their vinyloge derivatives are presented. Most of the compounds exist chiefly in the enol-form. Only in the case of 4-dimethyl-amino-dibenzoylmethane a keto-enol-equilibrium is registered. The influence of the substituent A and the chain-length on the position of the enol proton is discussed.
