Coordination Behavior Of New Bis

The compound aquapentaamminecobalt(III) Nitrate, [Co(NH3)5OH2] NO3, is a metal complex bonded to the molecule nitrate to attain a neutral charge. The synthesis of this molecule is a more complex one, requiring the recrystallization of an intermediate species. When the complex has been formed and isolated via filtration, the complex can be reacted with various aqueous solutions, one being dimethyl sulfoxide, C2H6OS. When reacted these reagents form the compound Co(NH3)5(OS(CH3)2)3+, H2O, and NO3-, though not inn this ratio. Specifically the aquapentaamminecobalt(III) molecule can be used to study the sixth coordination site on the molecule where the later is bound. Because of the weaker bond between the cobalt ion and the water

Hydrates are combinations that are salts with water particles synthetically clung to them. Really, the holding is intriguing in that the water particles bond specifically to the metal cation. Hydrates fall in an expansive class called coordinated compounds in view of the sort

1. Purpose: The purpose of the experiment is to determine the formula of an unknown hydrate by following simple steps that includes finding the moles of hydrate and anhydrate and then use the mole ratio to write the formula. 2. Introduction: A hydrate is a compound that contains water with a definite mass in the form of H2O. Hydrates are often in the form of a crystal that can be heated and the water can be 'burned off' by turning it into steam.

The molecular relationships consists of the bonding vibrations between specific elements. Carbon, hydrogen, and oxygen bonds are commonly witnessed in IR spectra. The focus on the bonding vibrations associated with these elements leads to IR’s use in organic chemistry. A key use of IR spectra is to determine functional groups within compounds and also to verify compound purity. For this experiment, the IR spectra will be used to determine plausible functional groups that exists in the samples. These functional groups will be verified or disregarded by the MS spectra ion fragment weights and the spectra produced by Hydrogen-1 and Carbon-13 Nuclear Magnetic Resonance Spectroscopy

A hydrated compound, is a compound that absorbs water molecules from the surrounding environment.1 The water molecules attach to the compound, but do not form a chemical bond. Water molecules in an inorganic hydrate can be released when the compound is heated, and become anhydrous.1

Bromide molecule from pyridinium tribromide was attacked by pi bond creating a positive charge on the bromide. To stabilize the structure, the negative bromide was introduced via frontside attack and made an syn product.

In this article, the hydrazones and their substituted species were studied to explore the essential factors influencing on their antimalarial activity. To this aim, we employed quantum theory approach, HF/6-31G* level of theory, and computed the NQCC parameter for all our candidates in this research. NQCC, as a powerful tool, was used here to predict the electronic charge density around the active sites that are susceptible to iron cation chelating.

Hydrazine or H2H4 is an extremely toxic unstable liquid that was first discovered by Theodor Curtius. In 1907 Freidrich Raschig was the persin to discover an efficent way to produce Hydrazine at an industrial level, this process is called the Olin- Raschig process. It is a man made molecule and is created by mixing sodium hypochlorite with ammonium to create chloramine and sodium hydroxide . Then is added anhydrous  ammonium which is put under presure and this produces hydrazine, water and salt as a by product . Hydrazine is a greta reducing agent and thr only by products are nitrogen and water. It is used to reduce plutoniuim waste back into its solid state. Also it is used as a precursor for organic synthese. In that process it is

Methyl orange is synthesized through an azo coupling reaction between a diazonium ion and N,N-dimethylaniline. An electrophilic aromatic substitution causes the positively charged diazonium ion to act as the electrophilic species.

The compounds of the transition metals react with negative ions and/ or neutral molecules to form transition metal complexes. Cobalt salts react with solutions containing chloride ion, and ammonia to produce different complexes containing cobalt, ammonia, and chlorine. A handout called “The Cobalt Complex Project-Synthesis” was given by the instructor. The experiment was carried out according to the detail directions written on the paper. The color of the solution didn’t change after dissolving ammonium chloride in concentrated aqueous ammonium hydrioxie. The solution’s color started changing after putting cobalt(II) chloride hexahydrate. While adding the concentrated aqueous hydrogen peroxide, the effervescences were formed. The color of the

Abstract A series of new 4-(1-azidoethyl)-1,1 '-biphenyl derivatives were synthesized by the metal-free reductive reactions of biphenyl tosylhydrazones and sodium azide. The resulting biphenyl derivatives were further reacted with aryl acetylenes to afford novel 1,4-substituted 1,2,3-triazoles in 41–94% yield by water-soluble salen-Cu(II) catalyzed azide–alkyne cycloaddition in water in the absence of any organic solvent or phase transfer agent. Moreover, the catalytic system exhibited wide substrate scope and high functional-group tolerances.

This heterogeneous catalyst can be applied to a wide variety of activated and non-activated primary and secondary alcohols. As shown in Table 3, benzyl alcohol and substituted benzyl alcohols are converted to their corresponding aldehydes efficiently. In the case of benzyl alcohol, after 30 min, only benzaldehyde was obtained in 99% yield. In longer reaction times (1h), the obtained products are 97% p-OCH3 benzaldehyde and 3% p-OCH3 benzoic acid. The results show that the substituent’s have no major effect on the oxidation of benzylic alcohols. A good selectivity experimental in the case of cinnamyl alcohol and only oxidized in alcoholic group and no epoxide yield was obtained. Manganese(II)non-heme was also used for oxidation of secondary alcohols and their corresponding ketones were obtained in good yields. We used hydrogen peroxide (H2O2) as the oxidant and [Mn(BPMP)(OTf)2] as the catalyst for the oxidation of alcohols. To a mixture of substrate (1mmol), manganese non-heme catalyst (1mol %), and solvent (CH3CN = 3mL) was added H2O2 (1.2mmol). The reaction mixture was stirred for 30 min at room temperature. This system has shown high catalytic activities for the oxidation of non-activated and activated alcohols under mild conditions as shown in Table 4. Secondary alcohols were easily converted to the corresponding ketones in excellent yields and reaction selectivity was over 99% in all cases. Cyclic alcohols
