Bis(pinacolato)diborano

Descripción:

Bis(pinacolato)diborano, comúnmente conocido como B2pin2, es un compuesto organoboro caracterizado por su estructura y reactividad únicas. Presenta dos átomos de boro cada uno unido a un grupo pinacolato, que se deriva del pinacol, un diol. Este compuesto es típicamente un líquido incoloro a amarillo pálido y es conocido por su estabilidad en condiciones ambientales, lo que lo convierte en un reactivo valioso en la síntesis orgánica, particularmente en la formación de compuestos que contienen boro. B2pin2 se utiliza a menudo en reacciones de acilo cruzado, como el acilo Suzuki-Miyaura, debido a su capacidad para servir como fuente de boro. Su reactividad se puede atribuir a la presencia de los átomos de boro, que pueden sufrir diversas transformaciones, incluida la oxidación y la coordinación con otros nucleófilos. Además, Bis(pinacolato)diborano es soluble en disolventes orgánicos comunes, lo que mejora su utilidad en entornos de laboratorio. Se deben observar precauciones de seguridad al manipular este compuesto, ya que puede ser inflamable y puede representar riesgos para la salud si se inhala o ingiere.

Bis(pinacolato)diboron

CAS: 73183-34-3

Bis(pinacolato)diboron is a versatile reagent that is used in organic synthesis. It is a boron-containing compound that inhibits the reaction between amines and hydroxide solutions, forming an intermediate copper complex with a carbonyl group. The mechanism of this inhibition has been explored and found to be due to the presence of a hydroxyl group on the bis(pinacolato)diboron molecule. Bis(pinacolato)diboron reacts with an amine to form an adduct containing a boron-nitrogen double bond. This intermediate then reacts with hydroxide ions from the solution to form the final product, which contains both an amine and hydroxyl groups. The isolated yield of this reaction is typically low, but can be increased by using palladium as a catalyst.
