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

substituents to aromatic rings. In the organic synthesis 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

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

Abortion One of the most constant battles our society faces is the issue of abortion. It is a controversial issue that continues to create tension and diversion among our culture. But what makes abortion such an emotional and personal conflict? Often time people aren’t fully aware of what takes place in the process of aborting a fetus. Let’s take a look at what abortion is and what makes it so controversial. By understanding what an abortion is and the different viewpoints of society‚ one will acquire
