    Diphenyl disulfide is usually prepared by the oxidation of thiophenol: . 2 PhSH + I 2 → Ph 2 S 2 + 2 HI Hydrogen peroxide can also be used as the oxidant. [2] Ph 2 S 2 is rarely prepared in the laboratory because it is inexpensive, and the precursor has a disagreeable odour.

    More so than thiophenol, benzeneselenol is easily oxidized by air. The facility of this reaction reflects the weakness of the Se-H bond, bond dissociation energy of which is estimated to be between 67 and 74 kcal/mol. [1] In contrast, the S-H BDE for thiophenol is near 80 kcal/mol. [3] The product is diphenyl diselenide as shown in this idealized equation:

  8. Diphenylmethane - Wikipedia

    en.wikipedia.org/wiki/Diphenylmethane

    The methylene group in diphenylmethane is mildly acidic with a pK a of 32.2, and so can be deprotonated with sodium amide. [3](C 6 H 5) 2 CH 2 + NaNH 2 − → (C 6 H 5) 2 CHNa + NH 3. The resulting carbanion can be alkylated.
