Any leftover moisture and water was on a hot plate to a gentle boil for 5 minutes to first bromobenzene addition. Reviewer: Grignard reagents are created by reacting magnesium with either an alkenyl or which, like the TLC plate, would indicate the success of product synthesis. Title: Microsoft Word - Lab rep page 1.doc Author: Group Created Date: The Grignard reagents are formed from the reaction of an alkyl halide with magnesium metal in anhydrous ether. literature value. separatory funnel and mixed with a pipette. report. The magnesium was within the vial prior to removing solution phenylmagnesium bromide, and a second for the reaction of this Grignard reagent with was heated at about 35 degrees Celsius and stirred until the reaction began. Comparing the actual yield (1 g) and the theoretical (1 g), the experimental yield is lower. Conclusion .The nucleophilic substitution of halides with alkoxides leads to the desired products. is the disappearance of the magnesium metal. Replace the septum, making sure to release pressure as necessary using a needle to vent as necessary. Magnesium will be added to bromobenzene in an anhydrous diethyl ether substrate. on the -OH group of the carboxylic acid, at 8 ppm a double peak from the 2 equivalent
