When heated at 200 deg C, cis- and trans-4'- and 2'-methoxystilbene-2-carboxylic acids have been converted into the title compounds in varying yields, as has trans-4'-hydroxystilbene-2-carboxylic acid.On the other hand, trans-4'-nitrostilbene-2-carboxylic acid affords 3-(4-nitrobenzyl)phthalide.Mass spectrometry provides a simple method of distinguishing between the dihydroisocoumarins and phthalides.
