    • -3. The solvent thf molecule is disordered over two positions and was refined isotropically. In order to keep the geometric parameters in reasonable ranges, bond length restraints of C-O = 1.40(1) and C-C = 1.50(1) Å as well as restraints of 2.5(1) Å for 1,3-distances were applied.

    • It appears that rather than attacking the iron atom, the nucleophilic siloxide reacts with the iodide ligand to form an [Fp, fragment and intermediate IOSiPh2Me. The complex iron anion subsequently reacts with one equivalent of FpI to give Fp2. We speculate that the intermediate silicon-containing species reacts with one equivalent of siloxide ligand to give disiloxane O(SiPh2Me)2 and NaIO. The disiloxane is also the major product when Na7 is treated with I 2. This can be thought of as analogous to the reaction of I 2 with OH, which results in IO3, I, and H 2O.[71] When the same reaction is carried out using FpBr rather than FpI, an identical outcome is observed. However, the formation of Fp2 and O(SiPh2Me)2 from Na7 and FpI is slow, with about 50% of the starting material left after stirring for two weeks at room temp

    • It is reasonable to assume that the final products of hydride abstraction for both the oxide 5b and the phosphanyl borohydride 2b will be cyclic dimers or polymers of the corresponding boranes. Nonetheless, the first intermediates following hydride abstractions are key species along the reaction pathways, and these are likely to be as described above.
