Dioxygen Activation by an Osmium-dihydride:  Preparation and Characterization of a d4 Square-Planar Complex

Exposure of OsH2Cl2(P i Pr3)2 to air or bubbling with pure O2 affords the dioxo-Os(VI) compound OsO2Cl2(P i Pr3)2 as result of a direct OO double bond activation reaction. This Os(VI) species is reduced in the presence of n-BuLi to the novel dioxo-Os(IV) derivative OsO2(P i Pr3)2, a rare example of...

This Os(VI) species is reduced in the presence of n-BuLi to the novel dioxo-Os(IV) derivative OsO2(P i Pr3)2, a rare example of a d4 square-planar compound.
