Deuterium labeling experiments (a) decarboxylation of 2,2-dimethyl 3-phenyl propanoic acid run in d2-TFE to determine if TFE was a catalytically active hydrogen atom donor. (b) Decarboxylation in d1-TFE showing that the proton from the carboxylic acid starting material is incorporated in the product.
