Experiment 8: Transition Metal Templated Cyclisation Reactions Aim of Experiment The aim of this experiment is to prepare tris-(ethylenediamine) nickel (II) and to use it in a templated macrocyclisation reaction to obtain an unknown compound, compound B. Introduction In this experiment the most common type of macrocyclic ligand is formed – a quadridentate ligand. A quadridentate ligand is a group which develops a chelate and contains four points of attachment which are nitrogen donor atoms in this case, and in most cases. Unfortunately, the productions of some macrocyclic ligands result in only low yields. However, this problem can be rectified via the template effect. It is mainly first row transition metals (Nickel(II) in this experiment) that …show more content…

The experiments were conducted online using Late Nite Labs. Materials: Because the experiments were conducted online there wasn’t any physical use of materials, only digital ones, for these labs to be performed. Only the registration for the website was needed to perform these online labs, as well as a desktop computer.

    The lab started off by measuring critical materials for the lab: the mass of an an empty 100 mL beaker, mass of beaker and copper chloride together(52.30 g), and the mass of three iron nails(2.73 g). The goal of this experiment is to determine the number of moles of copper and iron that would be produced in the reaction of iron and copper(II) chloride, the ratio of moles of iron to moles of copper, and the percent yield of copper produced. 2.00 grams of copper(II) chloride was added in the beaker to mix with 15 mL of distilled water. Then, three dry nails are placed in the copper(II) chloride solution for approximately 25 minutes. The three nails have to be scraped clean by sandpaper to make the surface of the nail shiny; if the nails are not clean, then some unknown substances might accidentally mix into the reaction and cause variations of the result.

    (1 point) What is the desired catalytic reaction and the primary undesired reactions and explain the enthalpy terms? The chemical equation representing the desired catalytic reaction is the selective hydrogenation of CO2 to produce methanol, which can be written as follows: CO_2 + 3H_2 → CH_3 OH + H_2 O In this equation, carbon dioxide (CO2) and hydrogen gas (H2) react in the presence of a catalyst to produce methanol (CH3OH) and water (H2O).

    They carry this charge due to them being more electronegative compared to the metal atoms. Carbon-carbon bonds can be created using these nucleophilic carbons. One kind of organometallic is a Grignard reagent. These reagents can create carbon bonds for long carbon-carbon chains. R-MgX is the general formula for a Grignard reagent.

    Next, the oxygen is protonated from the 3-nitrobenzaldehyde, which is then followed by an elimination reaction where this acts as a leaving group. The product is the trans-alkene present in the product. After the reaction was completed, purification of the product was conducted using semi-microscale recrystallization.

    This lab was done to see which of these elements were the most reactive. The order of the most reactive to least reactive would go like this: Magnesium was the most reactive with the solutions and reacted with all of the solutions in different ways such as bubbling with Mg(NO3)2, developed dark color with Cu(NO3)2, rusting with Ag(NO3)2, black dust coming off with Zn(NO3)2 and changed the solution’s color with Cu(NO3)2. Zinc was the second most reactive because it had the second most amount of reactions and reacted to the solutions by developing a dark ring and changing the solution's color with Cu(NO3)2 and creating a black dot in the middle with Ag(NO3)2. Copper is the third most reactive because it only reacted with Ag(NO3)2 by having the bottom of the surface change. Sliver is the least reactive because it didn’t react to any of the solutions.

    The Wittig reaction is valuable reaction. It has unique properties that allows for a carbon=carbon double bond to form from where a C=O double bond used to be located. Creating additional C=C double bonds is valuable due to its use in synthesis. The Wittig reaction will allow the synthesis of Stilbene (E and Z) from a Benzaldehyde (Ketcha, 141).
