Lauren Margerum 4/29/2007 Synthesis of Triphenylmethanol-A Gringard Reaction Purpose: To prepare triphenylmethanol and convert it to trityl fluoborate, a salt that contains the trityl carbocation. All of which will help to determine the kinds and positions of substituents on the parent triphenylmethyl ring structure, by examining the color of the purified triphenylmethanol. Chemistry: The following represents a general carbocation structure that will be used for this experiment: C - M e 2 N C l - An error incurred while manipulating the ring system using the chemistry sketch software, therefore the C - , should in fact be a C + . Materials: 100 mL round-bottom flask, Claisen adapter, West condenser, separatory- addition funnel, glass stopper, thermometer adapter with no rubber connector, drying tube with calcium chloride, flat-bottomed stirring rod, 50 mL Erlenmeyer flask, mortar and pestle, filter paper, burette clamps, hot plate, stir bar, vacuum filter flask, Bunsen burner rubber tubing, and a filtering funnel. Reagents: Magnesium turnings, bromobenzene, anhydrous ethyl ether, benzophenone, distilled water, 5% hydrochloric acid, 5% saturated aqueous sodium chloride, 5% aqueous sodium bicarbonate, and hexanes. Reactions: O O + H OH O OH 2 a c e t i c a n h y d r i d e a c e t i c a c i d 1
