Ethers made easy: Heating a solution containing a tosylhydrazone and either a phenol or an alcohol in the presence of K2CO3 leads to the corresponding ethers (see scheme; MW=microwave, Ts=tosyl). The reaction is fairly general for the preparation of aryl alkyl and alkyl alkyl ethers, and represents a new method for the reductive etherification of carbonyl compounds.
醚变得容易:在K 2 CO 3存在下加热含有甲苯磺酰s和苯酚或醇的溶液会生成相应的醚(参见方案; MW =微波,Ts =甲苯磺酰基)。该反应对于制备芳基烷基和烷基烷基醚是相当普遍的,并且代表了一种用于羰基化合物的还原醚化的新方法。
