| titleOfInvention | Process for preparing alkylidene-substituted-1,4-dions derivatives |
| abstract | A process for the preparation of a monoalkylidene substituted 1,4-dions derivatives of formula (Ia) or (Ib) or a mixture of (Ia) and (Ib): wherein: R1, R2 and R3, equal to or different from each other, are hydrogen atoms or C1-C20 hydrocarbon groups: T1 and T2, equal to or different from each other, are OR4. R4, NR42, SR4 or PR42; or T1 and T2 can be fused in an oxygen atom or a NR4 group; said process comprises the step of reacting a compound of formula (II), with a compound of formula (IIIa) or (IIIb), in the presence of at least one equivalent with respect to the compound of formula (IIIa) or (IIIb) of a salts of a base or a neutral base at a temperature higher than 70°C. |
