Organometallic chemistry

This experiment was performed in order to prepare the Grignard reagent from aryl or alkyl halides and demonstrate the principles of organometallic chemistry. The Grignard reagent was prepared via a radical mechanism. The Grignard reagent was then used to prepare a carboxylic acid from carbon dioxide, demonstrating its ability to create carbon-carbon bonds by acting as a strong nucleophile. As the R group of the Grignard reagent was unknown, molecular weight and melting point were then used to identify the resulting carboxylic acid. The molecular weight was determined using titration techniques and the melting point was measured using a Mel-Temp Apparatus. Data and Results In the formation of the Grignard reaction, the solution turned cloudy…

That question was the spark, that ignited this burning desire to know more about the world around us. As I progressed toward answering these questions I quickly realized that answers are complex and never as straight-forward as one might hope. Chemistry always gave the best context to answer my questions and explain the world around me. This context and understanding in turn allowed me to better help others. Throughout my journey so far in science and becoming a Chemist, those questions I…

Objective The purpose of the experiment is to synthesize a compound with an organometallic iron-carbon bond and use infrared spectroscopy to investigate the unconventional sandwich structure. In addition, the experiment aims to understand pi-bonding of an arene ring, use cyclic voltammetry to understand the redox capacity of ferrocene, and explore the barriers between formal inorganic and organic chemistry definitions. Introduction Ferrocene was discovered unintentionally in 1949 when…

Comparison of Organometallic Compounds of Transition Metals and Main Group Elements Organometallic Compounds: The compounds which contain at least one direct metal to carbon covalent bond are known as organometallic compounds many of these are thermodynamically unstable and are pyrophoric. The meta may belongs to main group, transition metal, f group metal or a metalloid i.e. selenium, boron, arsenic, silicon, antimony, germanium, and tellurium and the carbon moiety may be alkyl, alkene, alkyne,…

bond activation frequently occurs at transition-metal centers , often with high selectivity and trivial conditions. Our research group specializes in organometallic chemistry, most notably transition metal and actinide coordination complexes. Moreover, my graduate student mentor, Nicholas Klann, and I have begun developing a tripyrrole nickel coordination complex…

such us the photosynthesis (biology), organic synthesis (organic chemistry) or charge-transfer complexes (inorganic chemistry). It is important to know that most of the electron transfer occurs due to the metals, metals complexes and organometallic compounds. In this chapter a review of earlier electron donors and the different electron transfer will be developed. 1.1 Organic electron donors Since the earlier 1970s tetrathiafulvalene (TTF) organic compound has aroused great interest. TTF is an…

ii. Non-Acidic Oxygen Compounds Figure 3.4 Isomers of non-acidic oxygen compounds (Retrieved from Chemistry of Petrochemical Processes, 2nd Edition, 2001). C .Asphlathenes It is organometallic compounds and inorganic salts (metallic compounds). Mostly sodium, calcium, magnesium, aluminium, iron, vanadium, nickel are present either as inorganic salts, such as sodium and magnesium chlorides, or in the form of organometallic compounds, such as those of nickel and vanadium (as in porphyrins).…

functions in the area of:  analytical chemistry (environmental),  metallurgy,  biological systems,  industry  medicine. Coordination compounds has many applications in qualitative and quantitative chemical analysis. For the detection and estimation by classical and instrumental methods of analysis, the basis are provided by the common colour reactions given by metal ions. •Examples of such reagents include EDTA, DMG (dimethylglyoxime), α–nitroso–β–naphthol, cupron . Coordination…

reacted with oxiranes like ethylene and propylene oxides or alkylene carbonates like ethylene and propylene carbonates. The progress of reaction as well as structure of the products were studied by classic and instrumental methods like elemental analysis, IR, 1H-NMR, and MALDI-ToF spectroscopies. Some physico-chemical properties of the products were described. Keywords: carbazole, glycidol, oxiranes, alkylene carbonates, oligoetherols, properties Introduction Carbazole is aromatic three ring…
