Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 499-40-1, Name is (2R,3S,4R,5R)-2,3,4,5-Tetrahydroxy-6-(((2S,3R,4S,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)hexanal, SDS of cas: 499-40-1.
Synthesis, X-ray structure, and theoretical studies of novel cationic mono-cyclopentadienyl complexes of Co(III): The orthometalation of trans-azobenzene
New cationic mono-cyclopentadienyl complexes of Co(III) containing mono or bidentate nitrogen donor ligands of general formula [Co(eta5-C5H5)(PPh3)L2] [BF4]2 (L=NC-CH3, 2, and NC-Ph, 3) or [Co(eta5-C5H5)(PPh3)(L-L)][BF 4]2, [L-L=2,2?-bisimidazole (H2biim) (4) and dipyridylamine [HN(NC5H5)2] (5) have been synthesised by the stoichiometric reaction of the Co(III) complex Co(eta5-C5H5)(PPh3)I2 (1), with Ag[BF4] and the appropriate ligand in CH2Cl2. Under the same conditions and using trans-azobenzene as a ligand, an orthometalation reaction took place, giving the new compound [Co(eta5-C5H5)(PPh3)(kappa-C,kappa-N-C6H4N=NPh)][BF4] (6) in high yield. The structural characterisation of compounds 4 and 6, and of the starting compound Co(eta5-C5H5)(PPh3)I2 (1) was done by single-crystal X-ray diffraction studies. DFT calculations (ADF program) were performed in order to understand the orthometallation reaction.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.SDS of cas: 499-40-1. In my other articles, you can also check out more blogs about 499-40-1
