Abstract

The rational and high-yield synthesis of [(COD)Rh{(η²-BH₃)Ph₂PCH₂PPh₂}][PF₆] (1), which bears a chelating monoborane phosphine, is reported; the solid-state structure shows that the borane coordinates to the metal via two 2e-3c B-H-Rh bonds, which in solution at room temperature are fluxional between all three B-H bonds. Complex 1 is isolated as an air-stable crystalline salt, and its applicability as a catalyst in organic synthesis has been demonstrated in the coupling of boronic acids with enones.
