Salome, Christophe; Kohn, Harold published an article on January 10 ,2009. The article was titled 《Triphenylphosphine dibromide: a simple one-pot esterification reagent》, and you may find the article in Tetrahedron.Recommanded Product: 59410-82-1 The information in the text is summarized as follows:
We report a one-pot, expedient protocol for the conversion of carboxylic acids to their esters using excess triphenylphosphine dibromide, base, and the alc. The reaction gave the esterified product in moderate-to-high yields (30-95%). For chiral acids, the reaction proceeded with little or no racemization. Use of a chiral alc. in this transformation gave the ester with retention of configuration of the stereogenic center. Information is presented indicating that esterification proceeds through the intermediate generation of an acyloxyalkoxyphosphorane and where steric interactions play an important role in the energetics of the reaction.H-Phg-OEt.HCl(cas: 59410-82-1Recommanded Product: 59410-82-1) was used in this study.
H-Phg-OEt.HCl(cas: 59410-82-1) belongs to esters. They are important in biology, being one of the main classes of lipids and comprising the bulk of animal fats and vegetable oils.Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones.Recommanded Product: 59410-82-1
