Abstract

In general, the hydroboration of 1-alkynes gives alkenylboronates; the sequential regioselective hydroboration of alkenylboronates using pinacolborane providing 1,1-organodiboronates has never been reported. [7] The conventional reports concerning the hydroboration of CC multiple bond provides a regioisomeric mixture and reduction product as well as tri- and tetraboronates; thus the control of the regioselectivity and the inhibition of overreaction via ...
