Chelating monoborane phosphines: Rational and high-yield synthesis of [(COD)Rh{(eta(2)-BH(3))Ph(2)PCH(2)PPh(2)}][PF(6)] (COD=1,5-cyclooctadiene)

Chelating monoborane phosphines: Rational and high-yield synthesis of [(COD)Rh{(eta(2)-BH(3))Ph(2)PCH(2)PPh(2)}][PF(6)] (COD=1,5-cyclooctadiene)

The rational and high-yield synthesis of [(COD)Rh{(η2-BH3)Ph2PCH2PPh 2}][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 betwe...

Ամփոփում:The rational and high-yield synthesis of [(COD)Rh{(η2-BH3)Ph2PCH2PPh 2}][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.
