Conclusion: ¬¬The goal of the first part of this experiment was to achieve a 50-50 conversion of fluorene to Fluorenone. In order to achieve the goal of the experiment fluorene was oxidized to Fluorenone. The hydroxide ions from the sodium hydroxide in the presence of Stark’s catalyst would be able to de-protonate the acidic fluorene protons. This would result in the formation of a carbanion which attacks the oxygen from the air resulting in the formation of a hydroperoxide and eventually a ketone

Part 5: Synthesis‚ characterization and evaluation of COS-SMCC-(fatty acyl) CGKRK as in vitro gene delivery system to MDA-231 The delivery of siRNA is a great challenge due to its susceptibility to serum nuclease digestion‚ quick renal clearance. In addition to its anionic charge which hampers its cellular uptake. Therefore‚ the success of the gene carrier system relays on‚ the design of a delivery system that can protect siRNA molecules from enzymatic degradation‚ the ability to translocate the

ABSTRACT: The electrophilic aromatic substitution reaction is the attack of a benzene ring on an electrophilic species resulting in the substitution of a proton with a functional group. The electrophilic aromatic substitution reaction nitration is used to nitrate methyl benzoate and acetanilide with a nitronium ion. Crystallization was used to purify the product. The melting point was used to determine its purity and the regiochemistry of the products. The methyl benzoate reaction product‚ methyl

Abstract: Experiment 55 consists of devising a separation and purification scheme for a three component mixture. The overall objective is to isolate in pure form two of the three compounds. This was done using extraction‚ solubility‚ crystallization and vacuum filtration. The experiment was carried out two times‚ both of which were successful. Background Information: This experiment combined all the knowledge of the previous labs performed throughout the semester. An unknown mixture containing
