The invention relates to bimetallic complexes in which the ligand contains a salophen unit which complexes copper, manganese or cobalt and a phenanthroline unit which complexes palladium and the two systems are linked by a continuous conjugated system. The invention further relates to the use of these bimetallic complexes as catalysts for the oxidative carbonylation of aromatic hydroxy compounds to form diaryl carbonates, a process for preparing diaryl carbonates using the bimetallic complex as catalyst and also diaryl carbonates prepared by oxidative carbonylation of aromatic hydroxy compounds using the bimetallic complexes of the invention as catalysts.
该发明涉及双金属配合物,其中配体包含一个含有与铜、锰或钴形成配合物的萨洛菲单元以及一个含有与钯形成配合物的菲咯啉单元,两个系统通过一个连续的共轭系统连接。该发明还涉及将这些双金属配合物用作芳香羟基化合物的氧化羰基化反应的催化剂,以形成二芳基碳酸酯,使用双金属配合物作为催化剂制备二芳基碳酸酯的过程,以及使用该发明的双金属配合物作为催化剂进行芳香羟基化合物的氧化羰基化反应制备的二芳基碳酸酯。
