Benzyltrimethylammonium hydroxide benzil with dibenzyl ketone

Benzyl-l-decalone, 48, 43 2-Benzyl-2-methylcyclohexanone, 48,43 N-Benzyloxycarbonylglydne, 46, 49 2-Benzylperfluoropropene, 48,119 C i-2-BENZYL-3-PHENYLAZIRIDINE, 48,20 Benzyltrimethylammonium hydroxide as catalyst for condensation of benzil with dibenzyl ketone, 46, 45... [Pg.129]

Preparation. The reagent is readily prepared by the condensation of benzil with dibenzyl ketone in the presence of a basic catalyst. Dilthey s original procedure, adopted by Organic Syntheses specifies ethanol as solvent and a solution of potassium hydroxide in ethanol as the base. This procedure suffers from the low boiling point of the alcohol and the limited solubility of both potassium hydroxide and the reaction product in ethanol. In an improved procedure - use of the better solvent triethylene glycol permits operation at a higher temperature, and use of the readily soluble benzyltrimethylammonium hydroxide as base eliminates the step of dissolving potassium hydroxide in ethanol, A mixture of 0.2 mole each of benzil and... [Pg.1308]
