Multistep Synthesis of Tetraphenylcyclopentadienone In this laboratory experiment a synthesis was performed through several separate steps. The purpose of the experiment was to synthesize tetraphenylcyclopentadienone from benzaldehyde and to run reactions on carbonyl containing compounds. There was a total of three steps that led up to the synthesis of the final product‚ tetraphenylcyclopentadienone. The first step of the experiment was the condensation of benzaldehyde to yield

The effect of temperature on the reaction rate: As the temperature increases it provides more kinetic energy to the molecules allowing them to move faster and with more energy the molecules can overcome the activation energy barrier and therefore the reaction occurs faster. 5. Since the proposed mechanism is a SN1 reaction the reaction got faster as the polarity increased. This is because SN1 reactions work best with polar protic solvents as they stabilize the carbocation. Therefore‚ as seen

Oxidation of Cyclododecanol Bo Schuetz Chem 34l Section 004 10/29/2024. Introduction Goal: The objective of this experiment was to convert cyclododecanol‚ a secondary alcohol‚ into cyclododecanone‚ a ketone‚ through an oxidation reaction using sodium hypochlorite (NaClO) as the oxidizing agent. Oxidation reactions of alcohols are fundamental in organic synthesis‚ as they enable chemists to selectively introduce new functional groups‚ which can subsequently be used to build more complex molecules

These data are consistent with the structure of eugenol. In addition‚ the IR of the product from the simple distillation of cloves closely corresponds with that of an

one side and amide group on the other but also includes non-polar functional groups that consisted of the benzene ring and methyl group. Acetylsalicylic acid low polarity results from only containing a carboxylic acid and ester and the presence of alkenes in the benzene ring. Ibuprofen was the least polar out of all analgesic drugs because it only contains one carboxylic acid and non-polar functional groups. The behavior of these compounds in function of their structure and polarity were inversely

EXPERIMENT 1: REACTIONS OF ENOLATE IONS WITH CARBONYL GROUPS Aims In this experiment we used two techniques for the reactions of enolate ions with carbonyl groups. One technique used was Doebner reaction and the other technique used was Claisen-Schmidt reaction. Therefore the aim of this experiment is to synthesize trans p-methoxycinnamic acid and to synthesize dibenzalacetone via an aldol condensation reaction between acetone and benzaldehyde. The products would be recrystallized using ethanol

Hornes-Emmons-Wittig reagent to generate an enolate anion of trimethyl phosphonoacetate instead of a phosphorus ylide. The methyl trans-4-methoxy cinnamate produced is then analyzed using melting point and 1H NMR spectroscopy. Theory The Wittig reaction prepares alkenes from carbonyl compounds by attacking a phosphorus ylide with a nucleophilic carbon atom stabilized by a triphenylphosphonium group. An ylide is a compound that contains two oppositely charged atoms bonded together with complete octets and is generated
