One gram of phenylethylmethylpyrazolone in a little methyl alcohol is treated with a solution of 7 grams of 90 per cent, mercuric acetate (4 mols.) in 50 c.c. of methyl alcohol. The mixture is maintained at 60° C. and crystals separate in twenty-five minutes, are filtered after two hours, washed with acidified methyl alcohol, and dried. Yield 6 1 grams, 90 per cent. The substance has similar solubilities to the above 4-methoxy compound and decomposes above 200° C. It crystallises in prismatic needles, from which the mercury in the 4-position is removed by hydrochloric acid in the usual way, 3-Chloromercuri 4-methoxy-1 -dichloromercuriphenyl -3 -methyl -2 -ethyl -5 - pyrazolone being obtained, which has the structure ... 

A solution of 0.177g (0.468 mmol) [(2-(2 -furyl)phenyl)methoxymethylene]pentacarbo-nylchromium 53b in THF (150 mL) was photolyzed for 2 h with a 450 W medium-pressure mercury lamp with a pyrex filter while slowly sparging with CO. The yellow solution was stirred overnight under 1 atm of CO to effect decomplexation of the product from its tricarbonylchromium complex. The resulting colorless solution was concentrated in vacuo and the residue was purified by flash chromatography on silica gel (hexane/ethyl acetate, 75 25) to yield 0.095 g (95%) of 2-hydroxy-l-methoxy-furo[2,3-fc]naphthalene as a white powder.
