WebHydroboration can also be used to produce organoborane compounds which are chemical compounds which have carbon-boron bonds and are derivatives of BH3. These organoboranes can be reacted with some reagents to give alkyl halides, alcohols, and amines which are quite useful. Web14 mei 2013 · Hydroboration Of Alkynes Occurs With “Anti-Markovnikov Selectivity”, Giving Aldehydes From Terminal Alkynes There’s also hydroboration. Remember how hydroboration-oxidation of alkenes with BH 3 and H 2 O 2 gives us “ anti-Markovnikov ” hydration of alkenes?
