Compounds of the formula I ##STR1## in which p, m, Z, R, R' and Y are as defined in claim 1, can be obtained in a simple and economical manner by a novel process which comprises reacting a halide of the formula ##STR2## with the corresponding acrylic acid derivative, in the presence of a base and of certain palladium catalysts, such as palladium acetate. The compounds (I), and functional derivatives prepared therefrom, are useful for the preparation of photocrosslinkable polymers, which can in particular be employed as (so-called) photoresists.
公式I ##STR1## 中的p、m、Z、R、R'和Y的定义如权利要求1中所定义,可以通过一种新颖的方法简单经济地获得,该方法包括在碱和某些钯催化剂的存在下,将公式##STR2## 的卤化物与相应的丙烯酸衍生物反应,例如乙酸钯。这些化合物(I)及其制备的功能衍生物可用于制备光交联聚合物,特别可用作(所谓的)光阻剂。
