| 摘要 |
The invention relates to a process for producing 1,4-bisaryl-butane-1,4-diones having general formula (I) where R and R' independently denote substituted or unsubstituted aromatic or heteroaromatic groups and polymers thereof from 1,4-bisaryl-2-butyne-1,4-diols having general formula (III) where R and R' have the meanings stated above, and polymers thereof, by which process a compound having formula (III) or a polymer thereof is treated in a reaction medium having dissolution capacity for the starting compound having formula (III) or (IV), a pKA-value between 7.5 and 20, and capacity for donating H-atoms, by heating, preferably at reflux, to produce the desired compound having formula (I) or formula (II), whereafter the desired compound is isolated, if desired. |
