Quadruple Borylation of Terminal Alkynes

We present the first quadruple borylation reaction of terminal alkynes, affording functionalized 1,1,2,2-tetrakis(boronate) derivatives in a chemo-/regioselective manner. The methodology is operationally simple and a novel B–B bond activation without the need for a transition-metal catalyst.
