| | 2,2-Diphenylacetic acid Usage And Synthesis |
| 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 | | Definition | ChEBI: A monocarboxylic acid that is acetic acid where the methyl hydrogens have been replaced by two phenyl groups respectively. | | Synthesis Reference(s) | Journal of the American Chemical Society, 69, p. 2325, 1947 DOI: 10.1021/ja01202a023
