Tetrafenilborato di sodio

Descrizione:

Tetrafenilborato di sodio, con il numero CAS 143-66-8, è un composto organoboro caratterizzato dal suo anione tetrafenilborato abbinato a cationi di sodio. Si presenta come un solido cristallino bianco a giallo pallido ed è noto per la sua bassa solubilità in acqua, rendendolo più solubile in solventi organici come benzene e toluene. Questo composto è spesso utilizzato in chimica analitica, in particolare nella precipitazione di alcuni cationi, inclusi i metalli alcalini e i metalli di transizione, grazie alla sua capacità di formare sali insolubili. Tetrafenilborato di sodio è anche impiegato nella sintesi di vari composti organometallici e come reagente nella sintesi organica. La sua struttura presenta un atomo di boro legato a quattro gruppi fenilici, il che contribuisce alle sue proprietà uniche, inclusa la stabilità e la capacità di agire come un anione non coordinante. Devono essere osservate precauzioni di sicurezza quando si maneggia questo composto, poiché potrebbe comportare rischi per la salute se ingerito o inalato, e deve essere utilizzato un adeguato equipaggiamento di protezione.

Sodium tetraphenylborate

CAS: 143-66-8

Sodium tetraphenylborate is a chemical compound that is a salt of tetraphenylborate. It is used in the laboratory for the preparation of stable complexes with nitrogen atoms, including reaction solutions and light exposure. Sodium tetraphenylborate has been shown to be an effective catalyst for the Suzuki coupling reaction. The intracellular calcium concentration increases as a result of this reaction and this increase can be measured using titration calorimetry. This reaction also produces ester linkages in addition to hydroxyl groups, which are present due to the presence of a carboxylic acid group on one or more of the reactants.
