Used in Research and Development:
In academic and industrial research settings, triphenylmethylphosphonium is used as a reagent to explore new chemical reactions and pathways. Its stability and versatility make it an essential tool for advancing the understanding of organic chemistry and developing new synthetic methods.
Check Digit Verification of cas no
The CAS Registry Mumber 15912-74-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,9,1 and 2 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 15912-74:
(7*1)+(6*5)+(5*9)+(4*1)+(3*2)+(2*7)+(1*4)=110
110 % 10 = 0
So 15912-74-0 is a valid CAS Registry Number.

Reactions of Triphenylphosphine with Di-, Tri-, or Tetrasulphides, or with Sulphur, in Hydroxylic Solvents.
Demarcq, Michel C.
, p. 3052 - 3080 (2007/10/02)
In contrast to the behaviour of disulphides RS2R, the mono-desulphurisation of tri- or tetra-sulphides RSnR (R = benzyl, p-tolyl; n= 3, 4) by triphenylphosphine in hydroxylic solvents (methanol-benzene or water- 2-propanol-benzene) mainly affords Ph3PS with only small (n = 3) or very small (n = 4) amounts of Ph3PO.Ph3PO was virtually absent in the reaction products of Ph3P with 2Sn (n = 2, 3) or with elemental sulphur in alcoholic or aqueous media.Reaction rates for the formation of Ph3PS or Ph3PO decrease in the order: RS4R > RS3R >> RS2R (R = benzyl or p-tolyl) and hydroxylic >> aprotic solvents; the dependence on R is: (EtO)2P(S) >> p-tolyl > benzyl.Addition of a thiol impedes the formation of Ph3PO; low pH's have an opposite effect.The results are rationalised in terms of basicity of anions RSp- (p = 1 to n-1), relative softness of terminal or central S in RSnR and Broensted acidity of the solvent.An alternative is proposed to the Bartlett's mechanism for the reaction of S8 with Ph3P, in which the intermediate zwitterion Ph3P+S4- collapses by fast intramolecular nucleophilic displacement, affording Ph3PS and highly reactive S7.
