9,10-Dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO) is an organophosphorus compound that is used to produce fire retardants. From the chemistry perspective, it is a derivative of hypophosphorous acid as well as a derivative of phenanthrene. The reactivity of the P-H center allows for the conjugation of DOPO to many monomers.
Thiobenzophenone is an organosulfur compound with the formula (C 6 H 5) 2 CS. It is the prototypical thioketone.Unlike other thioketones that tend to dimerize to form rings and polymers, thiobenzophenone is quite stable, although it photoxidizes in air back to benzophenone and sulfur. [1]
Diphenyl diselenide is the chemical compound with the formula (C 6 H 5) 2 Se 2, abbreviated Ph 2 Se 2. This yellow-coloured solid is the oxidized derivative of benzeneselenol . It is used as a source of the PhSe unit in organic synthesis .
Ph 2 PH + n BuLi → Ph 2 PLi + n BuH The preparation of phosphine ligands , Wittig-Horner reagents , and phosphonium salts are commonly accomplished by alkylating diphenylphosphine. The hydrogen atom connected to phosphorus undergoes Michael-like addition to activated alkenes, providing products with which to produce phosphine ligands such as ...
Diphenyl sulfide is an organosulfur compound with the chemical formula (C 6 H 5) 2 S, often abbreviated as Ph 2 S, where Ph stands for phenyl. It is a colorless liquid with an unpleasant odor. Diphenyl sulfide is an aromatic sulfide. The molecule consists of two phenyl groups attached to a sulfur atom.

Ph 2 S 2 is rarely prepared in the laboratory because it is inexpensive, and the precursor has a disagreeable odour. Like most organic disulfides, the C–S–S–C core of Ph 2 S 2 is non-planar with a dihedral angle approaching 85°. [3] Ball-and-stick model of diphenyl disulfide. The S-S bond distance is 2.03 Å.
