The dinuclear oxorhenium complex of composition [(η5-C5Me5)ReO2]2 (1) is subject to clean cleavage upon treatment with aqueous hydrogen fluoride, chloride, and bromide, thus yielding the mononuclear halfsandwich complexes (η5-C5Me5)ReOX2 (X F, 2a; Cl, 2b; Br, 2c). The multistep mechanism of these reactions starts off with O-protonation of the Re2O2 core as demonstrated by an independent synthesis
