Premium Alkene Aldehyde
INTRODUCTION The purpose of this experiment is to synthesize trans-9-(2-phenylethenyl) anthracene from benzyltriphenylphosphonium chloride and 9-anthraldehyde through the reaction mechanism recognized as the Wittig Reaction. The Wittig Reaction allows the chemist to synthesize phosphoranes in the lab with relative ease. A more recent and inexpensive version of the reaction is the Wittig-Horner reaction (1). ABSTRACT Georg Wittig was a German chemist and Nobel Prize winner in 1979 for the Wittig

Adol Condensation Introduction: This reaction is carried out by adding benzaldehyde and acetone into a flask. The product created is a 1‚5-diphenyl-1‚4-pentdiene-3-one‚ which includes two double bonds‚ and two benzyl ring functional groups. This is a dehydration reaction that occurs twice in order to form the diene. After obtaining the product‚ via vacuum filtration‚ it will be recrystallized and then analyzed for purity by determining both products’ melting point. The two products will be

Nor Amirah Farhana Nawawi‚ Mia Organic Chemistry Lab Report 2 Jessica Sammons TITLE: Preparation of 2-butanone INTRODUCTION: The goal of this experiment was to prepare 2-butanone from 2-butanol. Chromic acid was used in this experiment to in order to prepare 2-butanol. Cr (VI) is rather orange‚ but Cr (III) is dark green - therefore by oxidizing the alcohol (2-butanol)‚ an orange Cr (IV) is reduced to green. NMR and IR tests were taken to determine the result‚ and the crystallized derivative of

Purpose: To synthesize 1‚2‚3‚4-tetraphenylnaphthalene through a two-step synthesis. The aldol condensation reaction between benzil and dibenzyl ketone forms 2‚3‚4‚5-tetraphenylcyclopentadienone‚ which then reacts with a benzene formed by anthranilic acid and isoamyl nitrate in order to yield 1‚2‚3‚4-tetraphenylnaphthalene. Reaction Equation A: Synthesis of 2‚3‚4‚5-tetraphenylcyclopentadienone: A solution of 4 capsules potassium hydroxide (0.5g) and 5mL anhydrous ethanol was prepared
