disiamylborane adds to a triple bond to give an alkenylborane. upon oxidation with oh–, h2o2, the alkenylborane will form an enol that tautomerizes to an aldehyde. in the first box below, draw the mechanism arrows for the reaction of disiamylborane with the alkyne, and in the last box draw the structure of the aldehyde.
