A production process for substituted phenylacetic acids or ester analogues thereof is disclosed. In this process toluene or toluene substituted with various substituents, an alcohol, an oxidant and carbon monoxide are used as raw materials to obtain compounds comprising structure of phenylacetic acid ester or analogues thereof by catalysis of the complex catalyst formed from transition metal and ligand, and such compounds are hydrolyzed to obtain various substituted phenylacetic acid based compounds. This type of compounds and their derivatives serve as important fine chemicals used widely in the industries of pharmaceuticals, pesticides, perfume and the like.
揭示了一种用于取代苯乙酸或其酯类似物的生产工艺。在这个工艺中,甲苯或带有各种取代基的甲苯、醇、氧化剂和一氧化碳被用作原料,通过过渡金属和配体形成的复合催化剂的催化作用,获得包含苯乙酸酯结构或其类似物的化合物,并且这些化合物被水解以获得各种基于取代苯乙酸的化合物。这类化合物及其衍生物在制药、农药、香水等行业中被广泛应用,作为重要的精细化学品。
