(HNL) catalyze the stereoselective addition ofhydrogen cyanideto aldehydes andketonesyieldingcyanohydrinproducts [38]. α-hydroxycarboxylic acids are then obtained by hydrolyzing the chiral cyanohydrins with hydrochloric acid. In this synthesis, quantitative conversion of an aldehyde into the cyanohydrins ...
Effenberger and Graef studied the regioselective hydrolysis of aromatic, aliphatic, and unsaturated dinitriles withRhodococcus speciesC3II andRhodococcus erythropolisMP50, both containing two enzymes inducing nitrile to amide transformation but also amide to acid conversion (Scheme 8).15Depending on the ...
We're going to have our toluene. We do Sulfonation with SO3 over H2SO4. That's going to add my sulfonic acid group to the para position since the methyl group is an ortho para director. So, I've blocked that para position. Now, we have an ortho para, sulfonic acid as...
1.An organic molecule containing a CN group, an organic derivative of hydrocyanic acid. 2.An oil-resistant copolymer of acrylonitrile and butadiene, used especially for disposable gloves, gaskets, seals, and tubing. Also callednitrile rubber. ...
Potential screening results reveal that 1a can be electroreduced from −1.1 V, corresponding to the LSV result. Although there is about 40% conversion of 1a at −1.0 V, the products are a mixture of amide and carboxylic acid hydrolysates rather than the desirable primary amine 2a....
Bacteria were grown on acetonitrile (10 mM) to induce the two-step nitrile hydratase–amidase pathway. Fig. 3 illustrates the initial conversion of acetonitrile at 2262.0 cm−1 to acetamide at 1667.5 cm−1/1598.0 cm−1 and then more slowly to acetic acid at 1553.5 cm−1/1416.6 cm−...

Normal pressure to 2 MPaG, preferably 0.1 to 0.5 MPaG The esterification of the carboxyl group-containing fluoroelastomer can be carried out under usual esterification conditions, for example, by a method of reacting the elastomer with an alcohol in the presence of an acid catalyst, a method of...
