laboratory‚ electrophilic aromatic substitutions which result in the formation of new carbon-carbon bonds are called ‘Friedel-Crafts’ alkylations and acylations‚ named for Charles Friedel of France and James Crafts of the United States‚ who together developed the procedures in 1877. The Friedel-Crafts reactions are an important part of a synthetic chemist’s toolbox to this day. Friedel Crafts reactions‚ like their biochemical counterparts‚ require reactive electrophiles with significant carbocation character

Friedel Crafts Alkylation Reaction Introduction: In the experiment we will create 1‚4-Di-t-Butyl-2‚5-Dimethoxybenzene by performing a Friedel-Crafts reaction on 1‚4-Dimethoxybenzene. In the reaction a t-butyl carbocation will be added on to the 1‚4-Dimethoxybenzene. The t-butyl carbocation will be formed by a reaction of t-butyl alcohol with sulfuric acid. To perform the reaction we will create a mixture of the 1‚4-Dimethoxybenzene‚ t-butyl alcohol with acetic acid. To this mixture we will

Introduction Friedel-Crafts acylation of anisole with acetic anhydride was used in this experiement to synthesize 4-methoxyacetophenone with the use of a reflux apparatus. Friedel-Crafts reactions can be done by alkylation‚ which involves mixing an alkyl or acyl halide with a Lewis acid‚ or acylation‚ which is done with acid chlorides or anhydrides(Lefevre). Acylation was used because it does not have as many disadvantages aklyations reactions have such as polyalkylation‚ second electrophilic attacks

Jessica Zebracki Organic Chem II Lab 2/15/15 Friedel-Crafts Acylation of Ferrocene and Column Chromatography Introduction: The intention of this lab is to analyze the formation of acetylferrocene using column chromatography. The Friedel-Crafts acylation reaction created acetylferrocene and diacetylferrocene‚ using phosphoric acid as a catalyst for the reaction between acetic anhydride and ferrocene (once applying heat). During column chromatography‚ a solution is passed through a filtration system

THE FRIEDEL-CRAFTS REACTION: ACETYLATION OF FERROCENE Ferrocene was acetylated in acetic anhydride and phosphoric acid. It proceeded via a Friedel-Crafts reaction without the use of organic solvents or strong Lewis acid. Operations and Observations A mixture of ferrocene (1.5 g‚ 0.008 mol)‚ acetic anhydride (5 mL) and phosphoric acid (1 mL 85%) was heated over a steam bath until all the ferrocene dissolved and the mixture darkened from orange to dark red. The mixture was then refluxed with

The alkylation of 1‚4-dimethoxybenzene is very favorable because of the presence of two methoxy groups. The groups act as activators to electrophilic aromatic substitution because of their ability to donate electrons through resonance. This enhanced activation helps favor the initial substitution. After this‚ the ring has two methoxy groups and an alkyl group attached to it. The addition of the alkyl group further activate the ring for another electrophilic aromatic substitution. The addition of
