Dimesitylborane, 1, is a readily available, solid, stable borane that is the most selective known reagent for the regioselective hydroboration of unsymmetrical alkynes.In addition all-alkynes are selectively hydroborated compared with even terminal alkenes.The hydroboration of alkenes with 1 is slow and sensitive to steric factors, thus giving promise of good selectivity between different types of alkene.
