Abstract
In the study of the interaction of homophthalic anhydride and methyl (triphenylphosphoranylidene)acetate, along with (1-oxo-1H-isochromen-3‑yl)acetate obtaining, two minor products – (1,3-dioxo-1,2,3,4-tetrahydronaphthalene-2-yl)acetate and 2‑((1‑oxo-1H-isochromen-3-yl)methyl)benzoic acid – had been isolated. The action of tert‑butyl (triphenylphosphoranylidene)acetate on homophthalic anhydride didn’t lead to Wittig reaction; the encumbered ylide demonstrated only its basicity, and products of homophthalic anhydride self-condensation – 2‑((1‑oxo-1H-isochromen-3-yl)methyl)-benzoic acid and 12-hydroxy-5H-dibenzo[c,g]chromen-5-one – were formed.
