2,3-dihydro-1H-indolizinium toluene-4-sulfonate is a chemical compound with the molecular formula C12H16N2+. It is an organic salt derived from the indolizine ring system, which is a seven-membered heterocyclic compound containing two nitrogen atoms. The toluene-4-sulfonate group is attached to the indolizinium cation, providing a negatively charged sulfonate ion (-SO3) that balances the positive charge of the indolizinium moiety. 2,3-dihydro-1H-indolizinium; toluene-4-sulfonate is often used as a reagent in organic synthesis and as a precursor in the preparation of various pharmaceuticals and dyes. Its properties include water solubility and the ability to form salts with other ions, making it a versatile building block in chemical research and development.

2400-85-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2400-85-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,4,0 and 0 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 2400-85:
(6*2)+(5*4)+(4*0)+(3*0)+(2*8)+(1*5)=53
53 % 10 = 3
So 2400-85-3 is a valid CAS Registry Number.

An efficient organocatalyzed interconversion of silyl ethers to tosylates using DBU and p-toluenesulfonyl fluoride

Gembus, Vincent,Marsais, Francis,Levacher, Vincent

experimental part, p. 1463 - 1466 (2009/04/07)

A mild and efficient interconversion from silyl ethers to sulfonates esters is reported with good yields. This silyl-sulfonyl exchange proceeds readily in acetonitrile at room temperature in the presence of p-toluenesulfonyl fluoride and a catalytic amount of 1,8-diazabicyclo[5.4.0]undec-7ene (DBU). This method can be used with trimethysilyl (TMS), triethylsilyl (TES) and tert-butyldimethylsilyl (TBDMS) ethers. Georg Thieme Verlag Stuttgart.
