Organoboron chemistry or organoborane chemistry studies organoboron compounds, also called organoboranes. These chemical compounds combine boron and carbon ; typically, they are organic derivatives of borane (BH 3 ), as in the trialkyl boranes.
La química de los compuestos de organoboro o química de los organoboranos es la química de estos compuestos. 1 2 Estos compuestos son reactivos importantes en química orgánica que permiten muchas transformaciones químicas, la más importante de las cuales es la hidroboración . Propiedades.
In organic chemistry, hydroboration refers to the addition of a hydrogen - boron bond to certain double and triple bonds involving carbon ( C=C, C=N, C=O, and C≡C ). This chemical reaction is useful in the organic synthesis of organic compounds. Hydroboration produces organoborane compounds that react with a variety of reagents to ...
Triethylborane ( TEB ), also called triethylboron, is an organoborane (a compound with a B–C bond). It is a colorless pyrophoric liquid. Its chemical formula is (CH3CH2)3B or (C2H5)3B, abbreviated Et 3B. It is soluble in organic solvents tetrahydrofuran and hexane . Preparation and structure.
Synthetic Reactions of Organoboranes; Mechanism of Oxidation of Alkylboranes; Contributors and Attributions; An especially valuable group of intermediates can be prepared by addition of an compound to carbon-carbon double or triple bonds: The reaction is called hydroboration and is a versatile synthesis of organoboron compounds.
Por esta razón, la reacción a menudo se considera una adición concertada de cuatro centros. Mecanismo concertado. La formulación paso a paso explica por qué el boro se adhiere al carbono menos sustituido, pero no explica el hecho de que las reacciones no muestran otras características de las reacciones de carbocatión.
Organoboranes and diboranes are central in organic synthesis, small molecule activation and catalysis, functional polymers, and neutron capture therapy.
