The decarboxylation of phthalide-3-carboxylic acid (3-oxo-l,3-dihydroisobenzofuran-1-carboxylic acid) has been studied in the melt, in dimethylsulfoxide, and in the presence of aromatic aldehydes. The latter are efficiently trapped to produce mixtures of 3-arylidene-phthalides and 3-(arylhydroxymethyl)phthalides. Kinetic and other evidence supports the proposal that this reaction occurs in a tight
