Equations 5.25ac on p. 193 show the formation of trialkylboranes from alkenes and BH3
Chapter 5, Problem 5.49(choose chapter or problem)
Equations 5.25ac on p. 193 show the formation of trialkylboranes from alkenes and BH3. In the reaction of 2,3-dimethyl-2-butene with BH3, only two equivalents of the alkene react, even with a large excess of alkene, to give a dialkylborane called disiamylborane. Give the structure of disiamylborane, and suggest a reason that only two equivalents of alkene react.
