Unformatted text preview: ORGANIC CHEMISTRY LANEY COLLEGE CHEM 12B Version 20090225 Grignard Reaction. Synthesis of Triphenylmethanol Reading Experiments 36, 36A in Pavia. See also Section 10.9 in Wade See also: General Grignard reagents react with ketones to yield tertiary alcohols. In this experiment you will generate a Grignard reagent from bromobenzene then allow it to react with a ketone, benzophenone. The procedure for Experiment 36 describes the formation of the Grignard reagent, where Experiment 36A describes the conditions for reaction of a Grignard reagent with benzophenone, which results in the formation of the tertiary alcohol. Prelab Include in your notebook the usual Title , Name , Date , Purpose , Chemical Equations (note the one above is not specific for this experiment), Reagent Table and an Outline . Note that the procedure you will follow is for Experiments 36 (formation of the Grignard) and 36A (reaction of the formed Grignard reagent with benzophenone), and although this is official two steps for the reaction you will not isolate the Grignard reagent...
