Benzoyl-l-phenyl-l-ethenyI 4-Methoxyphenyl TeUurium A 100-/w/, two-necked flask, fitted with a dropping funnel, a nitrogen inlet tube, and a magnetic stirrer, is charged with a solution of 4.7 g (10 mmol) of bis[4-methoxyphenyl] di tellurium in 10 m/ of absolute ethanol. The apparatus is flushed with nitrogen and 0.84 g (10 mmol) of sodium borohydride are added in small portions to the stirred solution kept at 20°. When the solution has become light yellow, a solution of 3.1 g (15 mmol) of phenyl(benzoyl)ethyne in 10 m/ of ethanol is added over 30 min to the stirred tellurolate solution. The yellow precipitate is filtered off yield 4.9 g (71%) m.p. 151° (from ethanol). 

Bis(3-methyl-2-benzoyl-l-phenyl-3-pyrazolin-5-one) has been reported as the product obtained from treatment of 4,4 -bis(3-methyl-l-phenyl-2-pyrazolin-5-one) with benzoyl chloride.1056... 

Acetyldibenzoylmethane (2-benzoyl-l-phenyl-l,3-butanedione) Benzoylacetone (16.2 g) and benzoyl chloride (14 g) are dissolved in anhydrous ether (100 ml), finely powdered anhydrous sodium carbonate (32 g) is added, and the mixture is set aside in a flask fitted with a reflux condenser and protected from moisture. The ether begins to boil in a short time. The mixture is set aside at room temperature for about 16 h, then the mixture of sodium chloride,sodium carbonate, and sodium enolate is filtered off, washed with ether, and whilst still moist with ether is dissolved in water. The ether is removed in a current of air, and precipitation by acetic acid then affords very pure acetyldibenzoylmethane (10 g). A further amount of enolate can be extracted from the ethereal mother-liquor by 10 % sodium carbonate solution, the total yield amounting to 87% (14 g). The pure product melts at about 110° 427...

Subjected to a mixture of nitric acid/acetic acid, ethyl l,4-benzodioxin-2-carboxylate did not lead to the expected 6-substituted product but led to a complicated mixture from which 52% of ethyl 3-nitro-l,4-benzodioxin-2-carboxyate was isolated <1997SC431>. Under acidic conditions, addition of water at the double bond of 2-phenyl-3-formyl-l,4-benzodioxin 33 afford an hemiketal which recyclized. After dehydration, the 2-benzoyl-l,4-benzodioxin 34 was isolated in very good yield <2000CHE351>.
