Abstract

A new catalytic system for the dehydrogenative oxidation of alcohols using a water-soluble Cp*Ir complex bearing a bipyridine-based functional ligand as catalyst has been developed. With this catalytic system, a variety of primary and secondary alcohols have been efficiently converted to aldehydes and ketones, respectively, in aqueous media without using any oxidant. Reuse of the catalyst by a very simple procedure has been also accomplished.

摘要

开发了一种使用水溶性 Cp*Ir 配合物作为催化剂的新型催化体系，用于醇的脱氢氧化反应，该配合物带有基于联吡啶的功能配体。在该催化体系中，各种伯醇和仲醇在水相介质中无需使用任何氧化剂即可分别有效地转化为相应的醛和酮。通过非常简单的程序即可实现催化剂的重复使用。
