The present invention provides a process for the preparation of aryl carboxylic acids and derivatives thereof by the carbonylation or diaryliodonium salts. The diaryliodonium salts are reacted with carbon monoxide and water of an alcohol or amine in the presence of a zero-valent metal catalyst consisting essentially of rhodium, ruthenium, and/or molybdenum.
本发明提供了一种通过羰基化或二芳基碘鎓盐制备芳基羧酸及其衍生物的工艺。 二芳基碘鎓盐在主要由铑、钌和/或钼组成的零价金属催化剂存在下,与醇或胺的一氧化碳和水反应。
