Chem323l Exp 8 Triphenylmethanol Prelab Lecture V2020 1 Youtube B) triphenylmethanol synthesis. the same setup as in the previous step is used. prepare a solution of 5 g of methylbenzoate in 15 ml of anhydrous ether and transfer this solution to the addition funnel. start adding this solution dropwise to the organomagnesium compound. when the addition is finished, reflux for another 30 min. Lab 7: synthesis of triphenylmethanol via grignard reaction. harrison chang chem 331l experiment 7 informal report april 10, 2021. abstract the purpose of this lab was to study the process of a grignard reaction through the examination of triphenylmethanol and its use in nmr spectroscopy. bromobenzene was first mixed with magnesium and. Discussion: the melting point for the product, triphenylmethanol, had a range of 151.8 156 as seen in the results. the literature value for triphenylmethanol is 164°c. 5 it is seen that the melting point range obtained for the product in this experiment was lower than expected due to impurities that may have been in the product. In tabular form, write the relevant physical properties (mp for solids and bp for liquids, solubility in ether and water) methyl benzoate, bromobenzene, and triphenylmethanol. 4. if you have the time before the start of the experiment, you might wish to set up the apparatus shown below in the procedure section.

In this experiment, you will perform two s n1 (substitution nucleophilic unimolecular) reactions using triphenyl methanol as your substrate (r l). the first one is the formation of the triphenylmethyl bromide from the reaction of triphenylmethanol with hydrobromic acid (figure 1). coh triphenylmethanol mp 163 oc m.w. 260.34 3 hbr h3o cbr. The grignard reaction is a useful synthetic procedure for forming new carbon carbon bonds. this organometallic chemical reaction involves alkyl or aryl magnesium halides, known as grignard reagents.1 grignard reagents are formed via the action of an alkyl or aryl halide on magnesium metal. grignard reagents react with electrophilic chemical.
