The preparation and ultraviolet absorption spectra of a number of methyl ethers and acetates of purpurogallin are given. The following derivatives of purpurogallin are, to our knowledge, not mentioned in the literature: a mono-acetate, m.p. 182-183 °C.; a diacetate I, m.p. 159–160 °C; a diacetate II, m.p. 208–209 °C.; a triacetate, m.p. 161.5–162.5 °C.; a monomethyl ether diacetate, m.p. 156–157 °C.; a dimethyl ether diacetate, m.p. 194-196 °C. Comparison of the ultraviolet absorption spectra with those determined for derivatives of known structure suggested the positions of the acetyl groups in the new substances now prepared.
