The major research question of my studies is if cyclooctyne can be successfully reacted with a vinylketene complex using a cost-effective methodology and in producing a distinct organic complex. In this experiment, a tricarbonyl iron(0) vinylketene complex was reacted with cyclooctyne in a cycloaddition reaction. The method used in this experimentation was based on the fundamentals of Click Chemistry. Since, reactions designed according to the concepts of Click Chemistry produced inoffensive byproducts and high yields, it was hypothesized that this reaction would produce a new methodology in how to synthesize cyclooctyne reacted complexes and produce an unknown organic complex. The primary goal in this research was to form an unknown* complex
Many sources of error were responsible for recovering a small amount of product. Introduction: The carbon-carbon bond formation is an important tool in organic chemistry to construct the simple as well as an organic compound. There are several
This is the result because The iodide displaces the chlorine forming 1-iodobutane. Since iodine is a much better leaving group than chlorine, 1-iodobutane will allow the cyanide ion to displace the leaving group much easier. The sodium ions will then ionically bond with the iodide ions to reform sodium iodide. This process lowers the total activation energy for the reaction. What would be the major product if 1,4-dibromo-4-methylpentane was allowed to react with one equivalent of NaI in Acetone?

Because of this, three different products (as previously mentioned) are potentially formed.1 The compound created from the reaction can be analyzed to determine
For this experiment, stereochemistry was observed by analyzing both the isomerization of dimethyl maleate and carvones. The dimethyl maleate is formed by two methyl ester groups that are connected by an alkene. They are in a cis-conformation meaning they are on the same side of the alkene, therefore the esters are close to one another. This conformation is strained and sterically hindered due to electrons repelling each other and are enantiomers of one another. With the use of radical chemistry, the cis conformation can be changed into a trans configuration where the esters are on opposite sides of one another.
In the talk, “Adventures in Organic Chemistry – Over Three Decades of Synthetic Organic Chemistry” presented by Dr. Chris Condeiu, he tried to relate the industry of organic chemistry to a students’ perspective. Three major points were drawn out through the talk. The first was the perspective of how capitalism drives the industry and the mechanism of doxycycline was formed. With an overview of his talk, the expectation was that a deeper understanding of how pharmaceutical drugs’ mechanisms are formed; instead, an insight of how the pharmaceutical industry can make one prosperous or just benefit the industry as a whole. Starting with the point about how capitalism governs the pharmaceutical industry, this relates to society in general.
Objective The objective of this experiment is to produce a sample of hexaphenylbenzene from the Diels-Alder addition of tetraphenylcyclopentadienone and diphenylacetylene, both of which were synthesized from previous lab procedures. Procedure Part A- Preparation of Hexaphenylbenzene • In a 25 mL round-bottom flask, 0.50 g (0.0013 mol) of tetraphenylcyclopentadienone and 0.50 g (0.0028 mol) of diphenylacetylene were poured, and with a heating mantle and a ring stand, the flask was vigorously heated.
Chem 51 LB Experiment 3 Report Scaffold: Bromination of Trans-Cinnamic Acid 1. The goal of this experiment was to perform a halogenation reaction through the addition of two bromides from pyridinium tribromide. This was accomplished by reacting trans-cinnamic acid with pyridinium tribromide. After the reaction took place, melting point analysis was conducted to find out the stereochemistry of the product, which could either be syn-addition, anti-addition, or syn + anti-addition. 2.
1- a. One aldehyde gives a positive iodoform test. Which one is it? • Ethanal b. Explain why ethanal gives a positive iodoform test. • Ethanal is the only aldehyde to give a the positive result because the reaction requires a methyl group connected to a carbon atom with a keto or an OH- substituent.
This letter formally serves as a request for aid in correcting an unknown issue with Joanie Steddum and with a possible violation of the Starbuck Bussiness Ethics and Compliance handbook from partners Joanie Steddum and Michael Spencer. Joanie 's constant use of an escalated toned, rude, offensive and aggressively mannered and Her preferred method of communicating with me has progressed to a manner in which I feel She is keeping me from exceeding the Legendary customer service standard expected of me. The Authoritative stance and demanding dialog, which also comes from Joanie, seems to be endured by others but I still have not yet seen her treat another partner so unwelcoming, rude, and as offensively and frequently as she has in the past with myself.
The core subjects of chemical engineering have applications in so many fields that a chemical engineer can apply his knowledge to many diverse areas. In this rich and vibrant research scenario, I want to combine core concepts with synthetic chemistry to solve challenging
The objective of this two-part experiment was to in Part I, create 4-tert-butylcyclohexanone via oxidation of 4-tert-butylcyclohexanol to provide a source of ketone for reduction procedures. Part II of the experiment was conducted preforming a series of reduction reactions in effort to asses the diastereoselectivity of aluminum isopropoxide (MPV reduction), sodium borohydride (NaBH4), and L-selectride when reacted with 4-tert-butylcyclohexanone. The methods used for analysis were TLC, IR, and 1HNMR spectroscopy. An oxidation of 4-tert-butylcyclohexanol was conducted to produce the ketone, 4-tert-butylcyclohexanone using oxidizing reagent, sodium hypochlorite in glacial acetic acid solvent.
Experiment 2 Report Scaffold (Substitution Reactions, Purification, and Identification) Purpose/Introduction 1. A Sn2 reaction was conducted; this involved benzyl bromide, sodium hydroxide, an unknown compound and ethanol through reflux technique, mel-temp recordings, recrystallization, and analysis of TLC plates. 2. There was one unknown compound in the reaction that was later discovered after a series of techniques described above.
Introduction Chevron Phillips Chemical Company is the major producer of Cyclohexane. This successful company hoses the three largest cyclohexane plants in the world. Many are puzzled by how the production of cyclohexane seems to have become stagnant. Perhaps this is due to the cost of benzene increasing or the demand increasing. Through thorough investigation, the answer to this question and many more can be answered.
The increase of the catalyst molar ratio to 0.05 and 0.10 mmol caused improvement in the rate of 1,2-cyclooctene oxidation with higher conversion compared to the catalytic amount 0.02 mmol of the VO-complexes. Unfortunately, the chemoselectivity was reduced by increasing the amount of the catalyst VO-complexes to be 65,
