Synthesis of trans-9-(2-Phenylethenyl)anthracene Introduction The purpose of this experiment was to convert carboxyl compounds into alkenes. While this reaction yields both the E and Z isomers‚ it is preferred over other reactions due to the lack of uncertainty of where the double bond is positioned. Also the stability of an ylide determines which isomer is the major product. 1 Experimental: Compounds Benzyltriphenylphosphonium chloride 9-Anthraldehyde 50% Aqueous NaOH DCM Product Formula weight

This produced a percentage yield of 85% from a theoretical yield of 2.638g. Introduction: Enantiomers are identical and equal in their physical properties except for optical rotation which can be viewed by polarimetry. Diastereomers have different densities‚ melting

OVERCOMING THE STATE INFLUENCED HEGEMONIC PRESSURE THROUGH MUSIC IN THE CASE OF EAST-WEST DIVAN ORCHESTRA In 1999‚ a Palestinian-American called Edward Said and a famous Argentina born Israeli conductor Daniel Barenboim founded East-West Divan Orchestra (Willson 347). Young musicians from Israel and Arabic countries were brought together to establish this orchestra. In other words‚ members from countries‚ cultures where there is a significant political conflict (Israel- Arabian Countries) had the

has several advantages: It gives only the trans product; it uses a much milder base that is easier to handle; and it gives a water soluble byproduct which is easy to separate from the product. The reason that these advantages occur is a change in the structure of the ylide. Instead of a tripheylphosphine ylide‚ we use a diethylphosphonate ylide. The protons are much more acidic and its byproduct is negatively charged. The reason why we chose to create trans-stilbene is become of its many practical

Case 15.1: Rotating Leaders: Orpheus Orchestra How are the concepts of substitutes for leadership and leadership neutralizers relevant to this case? Our OB book states that it has been proposed that there are substitutes for leadership that can diminish or replace the influence of leaders. Leadership neutralizer is defined as something that makes it impossible for leadership to make a difference. There are two instances which leaders will be less influential. The first is when subordinates have

For a long time‚ the research of foreign direct investment and trans-corporation mainly confine to the enterprises of manufacturing industry and most theories of international production are only fit for goods procuction. However‚ the fast development of service economy can’t permit us to ignore fact again‚ can’t permit our research to be only limited to the goods‚ but leave the question open to service. Gratifiedly‚ this kind of state is changing. On one hand it is because people have realized the

We‚ as musicians‚ are responsible for maintaining our ability to play at a consistent‚ near professional level. To accomplish this‚ we must practice. However‚ caught up in the excitement of my last high school summer‚ practicing my instrument was not as high on my priority list as it should have been. Having not been a member of this orchestra the previous year‚ I was unaware of the consequences I would face by not

RAIES! The purpose of this lab exercise was to perform the bromination of (E)-1‚2-diphenylethene (trans-stilbene) by addition reaction in which bromine was added across the double bond to yield a vicinal dibromide. The next step was to perform a double elimination reaction by product gained to synthesize an alkyne‚ that is‚ 1‚2-diphenylacetylene. The two major techniques used in this lab were TLC analysis and UV-vis spectroscopy. TLC technique is non-destructive‚ that is‚ the molecules in the mixtures
