Selective Esterification of Phosphonic Acids [PDF]

Molecules, 2021
Here, we report straightforward and selective synthetic procedures for mono- and diesterification of phosphonic acids. A series of alkoxy group donors were studied and triethyl orthoacetate was found to be the best reagent as well as a solvent for the performed transformations.

Esterification of p-hydroxybenzoic acid with glucose using a γ-Al2O3/SO4 catalyst [PDF]

Pharmaciana, 2019
Esterification of p-hydroxybenzoic acid with glucose can be expected to produce esters. The rate of esterification reaction is usually very slow and, therefore, needs an acid catalyst to accelerate it.

The synthesis of phosphinates: traditional versus green chemical approaches

Green Processing and Synthesis, 2014
Three alternatives are discussed in comparison with the classical esterification of phosphinic chlorides by reaction with alcohols. All novel methods, such as microwave (MW)-assisted direct esterification, MW-assisted phase transfer catalyzed alkylating ...
