General Description
Tritylium hexafluoroarsenate is a chemical compound with the formula (C19H15)AsF6. It is an arsenic-containing salt that is commonly used as a strong Lewis acid in organic synthesis. It is a stable and non-hygroscopic compound that is well-suited for reactions requiring a strong acid catalyst, such as Friedel-Crafts acylation and alkylation. Tritylium hexafluoroarsenate is also used as a reagent for the synthesis of various organic compounds and as a catalyst in the production of dyes and pharmaceuticals. Its stable and versatile nature makes it a valuable tool in the realm of organic chemistry.
Check Digit Verification of cas no
The CAS Registry Mumber 437-15-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,3 and 7 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 437-15:
(5*4)+(4*3)+(3*7)+(2*1)+(1*5)=60
60 % 10 = 0
So 437-15-0 is a valid CAS Registry Number.

Several tritylium compounds [Ph3C][A] have been isolated by salt metathesis or halide abstraction reactions starting from Ph3C-X (X = halogen) and Lewis acids in good yields (A = BF4, BCl4, AlCl4, GaCl4, PF6, AsF6, SbF6, SbCl6, CHB11H5Cl6, CHB11Cl11, CHB11H5Br6, CF3COO, CF3SO3, N3). The structures of 15 tritylium salts bearing different types of weakly coordinating anions (A-) have been determined. The structures are discussed on the basis of ion pairing versus covalent bond formation and solid-state interactions in comparison with gas-phase data.
