Usage

General Description

Triphenyl trithiophosphite is a chemical compound with the molecular formula C18H15PS3. It is a phosphorus-based compound that is used as a stabilizer and antioxidant in polymers and plastics. Triphenyl trithiophosphite is effective at preventing the degradation of polymers by free radicals, heat, and light. It acts as a chelating agent, capturing metal ions that can catalyze the degradation of the polymer. triphenyl trithiophosphite is also used as a co-stabilizer for improving the thermal and light stability of PVC (polyvinyl chloride) and other polymers. Additionally, triphenyl trithiophosphite is utilized in the production of lubricants, adhesives, and coatings as a way to enhance their thermal stability and resistance to oxidation.

Isotope Effects on 31P Nuclear Shielding in Thiophosphites

The 34S isotope effect on the chemical shift of PIII nuclei in P(SR)3 esters is close to 20.6 ppb per PIII-34S bond, i.e. 3-4 times larger than for thiolo sulphur atoms in S=P(SR)3.A similar behaviour is noted for the P(-S-)3 sites in P4S9 and P4S3 and for the downfield triplet of P4S8, which, accordingly, is assigned to the tri-coordinate P atoms of this sulphide. 13C isotope effects are also reported for trialkyl(aryl) phosphorotrithioites and S,S,S-phosphorotrithioates.

Synthesis, structure, and reactivity of a stabilized phosphiranylium salt

Chargedl Combining MeBABAR-Phos and methyl triflate affords an amino-stabilized phosphiranylium ion (see picture; C. gray, N blue, P orange), which undergoes various nucleophilic addition reactions to give P-substituted phosphiranes and an N-heterocyclic carbene stabilized phosphiranylium cation.
