for generating thioesters from carboxylic acids and thioesters. This transformation features operational simplicity and high step-economy, wherein the −SR moiety of thioesters was smoothly transferred to carboxylic acid from thioacetates as the starting material. Various substrates with different levels of electronic nature were all applicable to this reaction, furnishing thioesters in moderate to

self-supported Rh2A4 species has been prepared by reductive ligation of RhCl3 with adamantane-1,3-dicarboxylic acid. The catalyst has been demonstrated to be suitable for a range of nitrenetransferreactions, while also being suitable for carbenetransfer. Importantly, the catalyst can be made in a one-pot two step procedure and used directly, as well as being reusable.
通过RhCl 3与金刚烷-1,3-二羧酸的还原连接制备了一种新的自支撑Rh 2 A 4物种。该催化剂已被证明适用于一系列氮烯转移反应,同时也适用于卡宾转移。重要的是,该催化剂可以通过一锅两步程序制备并直接使用,并且可以重复使用。
