    • The numbering system adopted corresponds to the Chem. Abstr. numbering of the analogous 12H-dibenzo[d.g][1,3,2]dioxaphosphocin ring system. The C(12) bridging carbon atom corresponds to C(10) in the X-Ray crystal structure of 3.

    • The magnitude of the geminal coupling constant for the C(12) methylene protons (14 Hz) in 4 is consistent with the solution conformation being either a TB or a BC in rapid equilibration with a TB conformer.

    • Quite recently, Holmes has reported that an electronic effect (coordination of sulfur to silicon) in addition to a steric effect may be responsible for the BB conformation found for analogs of 5, see T.
