2,2-Diphenylacetic acid Chemical Properties,Uses,Production
Chemical Properties
white to creamy-white crystalline powder
Uses
Kinetic resolution of racemic 1-heteroarylalkanols by asymmetric esterification using diphenylacetic acid with pivalic anhydride and a chiral acyl-transfer catalyst is described. Molecular crystal of acridine and diphenylacetic acid and its absolute asymmetric photodecarboxylating condensation generates chirality in a two-component. The activation parameters for the racemization of a series of ortho-alkyl-substituted diphenylacetic acids are determined.
Definition
ChEBI: A monocarboxylic acid that is acetic acid where the methyl hydrogens have been replaced by two phenyl groups respectively.
