Grignard Addition VCL 10-1: Grignard Addition - 1 For this assignment, the target compound that you should synthesize is 1-phenyl-1-propanol. This is an organometallic addition reaction. Examine the product and identify potential bonds that may be formed. Keep in mind the mechanism and the need to quench the reaction with acid to liberate the neutral product. Synthesis Procedures 1.

Draw a “roadmap” of the experiment, containing chemical
structures and “layers” (organic and aqueous). This should contain
the individual reactions occurring in each step, and show which
layer the various components are present. Make sure you think about
whether the acetaminophen, caffeine and aspirin are neutral,
protonated or deprotonated.

Grignard reagent THE GRIGNARD REAGENT-PREPARATION AND REACTION In this experiment, you will prepare a Grignard reagent, phenyl magnesium bromide, from bromobenzene and magnesium metal. The Grignard reagent will then react with methyl benzoate to form triphenylmethanol. Introduction Grignard reagents, such as organomagnesium halides, were discovered in 1910 by French chemist Victor Grignard. The Grignard reaction is one of the most general methods for carbon- carbon bond formation in all of organic chemistry....

PROCEDURE Preparation oft-Pentyl Chloride In a 125-mL separatory funnel, place 10.0 mL of tert-pentyl alcohol (2-methyl-2- butanol, MW = 88.2, d = 0.805 g/mL) and 25 mL of concentrated hydrochloric acid (d 1.18 g/mL). Do not stopper the funnel. Gently swirl the mixture in the separa- tory funnel for about 1 minute. After this period of swirling, stopper the separatory funnel and carefully...

Experiment 7: Grignard Reaction. Introduction Discovered by French chemist Victor Grignard, the reaction that now bears his name is an example of the preparation of an organometallic reagent. In this lab, phenylmagnesium bromide is the Grignard of interest, and it will be added to an aldehyde to produce an alcohol. Lab Objectives 1. To study organometallic reagents in general. benzophenone. 2. To prepare phenylmagnesium...

Organic chemistry post-lab question: "Why is important
to add the alkyl halide dropwise in your reaction? (Hint: your
reaction is not heated, but you still need a water-cooled
condenser!)" Please answer in detail!
Here is a copy of the experiment, thank you!
The Grignard reaction is an important synthetic process by which a carbon-carbon bond is formed. Magnesium metal is first reacted with an organic halide. The resultant organo-magnesium halide (Grignard reagent) is then combined with a carbonyl compound, ultimately...
