2,2-Diphenylacetic acid Chemical Properties,Usage,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ChEBI: A monocarboxylic acid that is acetic acid where the methyl hydrogens have been replaced by two phenyl groups respectively.
