Process for the preparation of 2-cyano-3,3-diarylacrylates |
| abstract |
The preparation of 2-cyano-3,3-diarylacrylates I ##STR1## (in which Ar 1 and Ar 2 are aromatic radicals and R is an aliphatic radical having from 3 to 30 carbon atoms) by reacting a 2-cyano-3,3-diarylacrylate II ##STR2## (in which R 1 is methyl or ethyl) with an alcohol III n n R--OH (III) n n in the presence of a basic catalyst with removal of the alcohol R 1 -OH formed. n The esters of formula I are valuable UV absorbing agents for, say, plastics materials. |
