Question
This element forms the core of an introductory organic reaction that can hydrate an alkene in an anti-Markovnikov fashion. For 10 points each:
[10e] Name this element that, in its neutral form, contains an empty p orbital that can act as a Lewis acid for THF. This second-row trivalent element sits to the left of carbon.
ANSWER: boron
[10h] Boron is bonded to this glycol molecule, forming a boronic ester group whose diborane dimer is desirably stable. A 1,2-alkyl shift appears in a reaction named for this diol that converts to a carbonyl.
ANSWER: pinacol [or boronic pinacol ester; accept pinacol rearrangement; prompt on Bpin or B2pin2]
[10m] The Bpin boronic ester group can be used as a coupling partner in this palladium-catalyzed coupling reaction. This reacton’s namesake won the 2010 Nobel Prize in Chemistry with Heck and Negishi.
ANSWER: Suzuki-Miyaura reaction
