Archives for Chemistry Experiments of 79-33-4

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 79-33-4 help many people in the next few years. Formula: C3H6O3.

Let¡¯s face it, organic chemistry can seem difficult to learn. Especially from a beginner¡¯s point of view. Like 79-33-4, Name is L-Lactic acid. In a document, author is Banerjee, Abhisek, introducing its new discovery. Formula: C3H6O3.

A N2O4 donor compartmental reduced Schiff base ligand, H2L [(2,2-dimethyl-1,3-propanediyl)bis(iminomethylene)bis(6-methoxyphenol)], obtained on 1:2 condensation of 2,2-dimethyl-1,3-propanediamine with ortho-vanillin followed by reduction with NaBH4 in methanol solution, has been used to prepare two cobalt complexes, [(N-3)(CoL)-L-III(mu-OAc)Co-II(N3)] (1) and [(mu-N-3)(2){(AcO)(CoLNa)-L-III(CH3OH)}(2)]2CH(3)OH (2). Complex 1 is a dinuclear mixed valence cobalt(III)/cobalt(II) complex with (CoO2CoII)-O-III core. Complex 2, on the other hand, is a tetranuclear cobalt(III)/sodium complex with CoO2Na(N-3)(2)NaO2Co core. Formation of complex 1 or 2 is mainly governed by the amount of cobalt(II) precursors present in the reaction mixture. Each complex has been characterized by elemental and spectral analysis. X-ray diffraction analysis has confirmed their structures. Complex 1 crystallized in a chiral space group Pna21 where both the cobalt(III) and cobalt(II) centers adopt six-coordinate distorted octahedral geometry with cobalt(III) and cobalt(II) centers residing respectivelyat inner N2O2 and outer O-4 cavities of the reduced Schiff base. Complex 2 crystallized in triclinic system with P1space group, where both cobalt(III) and sodium centers adopt distorted octahedral geometry. Oxidation states of cobalt centers have been confirmed by bond length consideration, BVS calculations as well as from room temperature magnetic moment measurement. Both complexes 1 and 2 show phenoxazinone synthase mimicking activity with kcat values 250.21 and 493.73 h(-1) respectively.
