Ultrasound-Assisted Methyl Esterification of Carboxylic Acids ACatalyzed by Polymer-Supported Triphenylphosphine
© Georg Thieme Verlag Stuttgart · New York. A convenient and efficient sonochemical method for methyl esterification of carboxylic acids catalyzed by polymer-supported triAphenylphosphine (PS-Ph 3 P) is reported. In the presence of 1:0.1:2 molar ratio of 2,4,6-trichloro-1,3,5-triazine/PS-Ph 3 P/Na 2...

In the presence of 1:0.1:2 molar ratio of 2,4,6-trichloro-1,3,5-triazine/PS-Ph 3 P/Na 2 CO 3 , methyl esters of various carboxylic acids bearing reactive hydroxyl groups as well as acid-or base-labile functionalities could be rapidly prepared (within 10-20 min) in good to excellent yields without necessity to pre-activate the acids. Using the polymer-bound phosphine also allows easy isolation of the products which, in most of the cases, were obtained in high purities without column chromatography. 2018-01-24T04:39:19Z 2018-01-24T04:39:19Z 2015-09-01 Journal 14372096 09365214 2-s2.0-84939563711 10.1055/s-0034-1381117 https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=84939563711&origin=inward http://cmuir.cmu.ac.th/jspui/handle/6653943832/44201 |
