Ruthenium (Ru) is a transition metal element in-group 8, period 5, block d of the periodic table. It has an atomic number of 44 and is in a triad with Iron and Osmium. It was discovered independently in the residues left after crude platinum had been dissolved in aqua regina [1]. Ruthenium is one of the rare metals on earth and is generally found in the solid state [1]. It is generally found uncombined in nature although it is most commonly found associated with other platinum metals. It can also

check the pH and to verify the basicity of the solution. The aqueous layer was again drawn out from the solution. Next, 0.5g of sodium sulfate was added to the remaining organic layer and was swirled until the liquid appeared to be dry and clear. The alkenes were transferred into a clean 10mL flaks using another clean pasture pipe. The apparatus from the first distillation was rinsed off with

1. We used TLC analysis to identify each product obtained from the dihydroxylation reactions by spotting a TLC plate with the product of our reaction, a solution of cis-cyclohexane, trans-cyclohexane, and a 50:50 mixture of the two. We then placed the plate in a beaker with ethyl acetate saturating the atmosphere to allow the TLC plate to develop. Finally, we compared Rf values of the components of the mobile phase, after the phase was completed. 100% ethyl acetate was used instead of 100% Hexane

7) Discussion: In this experiment, the reactivity of alkenes with bromine was tested. The alkene used for this experiment was E-Stilbene. The expected mechanism of the reaction would be that the π electrons of the alkene would attack a bromine resulting in a carbon-bromine bond, a carbocation and a bromine anion. From this transition state, two things could happen. The first is that the bromine bonded to a carbon will attack the carbocation forming a bridged bromonium ion or it will remain as a

Click Chemistry and Application Zhuo Wang Abstract: Discuss the history, mechanism and application of “Click chemistry”. Through the introduction of “Click chemistry”, demonstrate the role it plays in chemical biology filed, the typical synthesis way of this concept, and current application in drug synthesis and research. Keywords: Click chemistry, vivo system, Huisgen 1,3-dipolar cycloaddition, CuAAC, Diels-Alder reaction Introduction: The phrase "click chemistry" was invented by K. Barry Sharpless

The goal of this experiment is to create a secondary bromide compound, 2-bromohexane, by adding 48% hydrobromic acid to 1-hexane using the methods of microscale extraction and reflux. Initially, add 0.5 ml of 1-hexene, 2.0 ml of 48% hydrobromic acid, and 150 mg of tetrabutylammonium bromide to a conical vial. According to Markovnikov’s Rule, the combination of these solutions theoretically should result in the formation of a 2-bromohexane product. This product forms due to the reflux process involved

Reaction Introduction: The Wittig reaction, named after Georg Wittig, produces an alkene from an aldehyde or ketone reacting with a phosphonium ylide (a Wittig reagent). The Wittig reaction is typically stereoselective, which makes the Wittig reagents more difficult to work with but use of the Wittig with different allyl substituents prove to make the Wittig more versatile which can lead to the synthesis of a wide range of alkenes, styrenes, stilbenes, and 1,3-dienes which can then be used to synthesize

hydroxyl groups, and an alkene group. The two-carbon branch expanding from the ring structure has two hydroxyl functional groups branching out. The molecular formula of Vitamin C is C6H8O6. This vitamin’s functional groups include one ester group, four hydroxyl groups and one alkene group. The rest of the molecule is hydrocarbon. Polarity Vitamin C is a polar molecule. This vitamin contains one polar ester functional group, four polar hydroxyl groups, and one non-polar alkene group. The rest of the

An E1 reaction is a type of elimination reaction in which two substituent groups are removed from a molecule via a two-step mechanism1. One feature of a E1 reaction is the carbocation intermediate. A carbocation is a carbon that has three bonds and a positive charge, but these carbons are very unstable and more reactive because they want to be stabilized. Carbocations can be stabilized with neighboring carbon atoms1. The stability of a carbocation increases as it changes from primary

natural products was a steam distillation and extraction. The amount of eugenol that was recovered 2.39 grams. After the recovery of eugenol, an IR spectrum was obtained. The IR spectrum displayed the presence of an alcohol at 3529.37 cm-1 and an alkene at 1638.08 cm-1. Classification tests are used to determine what is present.The results for the classification tests for eugenol are shown below in the table. Cyclohexene Sample Cyclohexane
