Syntheses and Characterization of a New Cyano-Substituted Bis(pyrazolyl)borate and its Thallium (I) ComplexAcquah, Chris 01 December 2016 (has links)
Scorpionates are versatile and flexible ligands with a wide range of applications including catalysis, C-H bond activation, formation of new class of materials, and mimicking enzymatic reactions. This is as a result of its steric and electronic properties, and due to the relative ease with which the 3, and 5-positions of the pyrazole ring can be functionalized. In this work, we report the synthesis of a new class of scorpionate ligands known as cyanoscorpionates which can crosslink various metal centers. Thus, bis (4-cyano-3,5-diphenylpyrazolyl)borate BpPh2,4CN was synthesized and fully characterized by 1H NMR and FT-IR. Coordination of bis (4-cyano-3,5-diphenylpyrazolyl)borate BpPh2,4CN to thallium (I) metal was performed and characterized and we are looking to elucidating its molecular structure by X-ray crystallography in future.
