Organoborane chemistry
Organoboron chemistry or organoborane chemistry is the chemistry of organoboron compounds or organoboranes, which are chemical compounds of boron and carbon that are organic derivatives of borane (BH3), for example trialkyl boranes. . Organoboron compounds are important … Zobacz więcej The C-B bond has low polarity (the difference in electronegativity 2.55 for carbon and 2.04 for boron), and therefore alkyl boron compounds are in general stable though easily oxidized. In part … Zobacz więcej Organoboranes and hydrides Among the most studied classes of organoboron compounds have the formula BRnH3−n. As discussed above, these compounds … Zobacz więcej Boranes alone are generally not nucleophilic enough to transfer an alkyl group to an electrophilic center. However, after nucleophilic attack, the resulting borate is highly … Zobacz więcej TEB – Triethylborane was used to ignite the JP-7 fuel of the Pratt & Whitney J58 variable cycle engines powering the Lockheed SR-71 Blackbird. Zobacz więcej From Grignard reagents Simple organoboranes such as triethylborane or tris(pentafluorophenyl)boron can be prepared from Zobacz więcej Organoboranes (R3B) and borates (R4B , generated via addition of R to R3B) possess boron–carbon bonds that are polarized toward carbon. Thus, the carbon attached to boron is nucleophilic, and in borates this property may be harnessed to transfer one of … Zobacz więcej The scope of organoboranes and borates as reagents for organic synthesis is extremely wide. Reactions of organoboron compounds may produce alcohols, carbonyl … Zobacz więcej WitrynaAbstract: The chemistry of "frustrated Lewis pairs" (FLPs) has become a rapidly evolving field since it was introduced 6 years ago. It offers new strategies for small molecule activation and organic synthesis which have long been dominated by transition metals. This chapter focuses on the recent development of organoborane compounds and …
