Phenylmagnesium bromide (PhMgBr) solution is an organomagnesium reagent mainly used in Grignard reaction, which finds application as the key step in the synthesis of (S)-2(diphenylmethyl)pyrrolidine, a chiral solvating agent for the NMR analysis.
What is the molecular formula for Phenylmagnesium bromide?
C6H5MgBr
Phenylmagnesium bromide/Formula
Is Phenylmagnesium bromide a liquid?
It is commercially available as a solution in diethyl ether or tetrahydrofuran (THF). Phenylmagnesium bromide is a Grignard reagent. It is often used as a synthetic equivalent for the phenyl “Ph−” synthon….Phenylmagnesium bromide.

What is the boiling point of Phenylmagnesium bromide?
65-67° C
Boiling Point : 65-67° C (lit.)
What product results of Phenylmagnesium bromide is exposed to water?
C6H5MgBr + H2O = C6H6 + MgBr(OH) Phenylmagnesium bromide (C6H5MgBr) reacts with water and produce benzene (C6H6) as the product. Also, we can say, C6H5MgBr hydrolysis and form benzene as a product.
How do you make Phenylmagnesium bromide?
Preparation of phenylmagnesium bromide: Place 2 g of magnesium turnings and 15 ml of anhydrous ether in a dry round-bottom flask. The necessary elements are coupled for reflux under anhydrous conditions and with the addition of reagents (see Figure 4.14 in p. 101).

Why must all equipment and reagents be dry when preparing Phenylmagnesium bromide?
You must keep your reaction apparatus and reagents completely dry because water functions as an acid, and would cleave the Grignard reagent producing benzene. All glassware must be thoroughly clean and dry.
What is the melting point of Phenylmagnesium bromide?
Reduction agent for preparation of metal carbonyl compound After the resulting gas was cooled, he could obtain colorless liquid (melting point 298K, the boiling point of 316K); if this gas is flowed through a heated glass tube, then it can be seen that the metallic nickel was deposited on the wall.
When Phenylmagnesium bromide reacts with T butanol the product would be?
Butanol is a modest tertiary alcohol. Complete Step by step answer: When Phenyl magnesium bromide reacts with t-butanol it produces benzene it is because phenyl group is an electronegative group which is associated with the active hydrogen of alcohol that is, -H of -OH group of alcohol.
