Benzenemethanesulfonyl bromide, also known as alpha-toluenesulfonyl bromide or tosyl bromide, is a chemical compound with the formula C7H7BrSO2. It is a colorless crystalline solid that is soluble in organic solvents such as ethanol, acetone, and dichloromethane. Benzenemethanesulfonyl bromide is widely used as a reagent in organic synthesis, particularly in the protection of alcohols and amines, as well as in the formation of sulfonamide derivatives. It is also employed in the preparation of various pharmaceuticals and agrochemicals. Benzenemethanesulfonyl bromide is a valuable tool in the field of chemistry due to its ability to introduce a tosyl group, which can be selectively removed under mild conditions, making it a versatile protecting group in organic synthesis.

17075-10-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 17075-10-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,0,7 and 5 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 17075-10:
(7*1)+(6*7)+(5*0)+(4*7)+(3*5)+(2*1)+(1*0)=94
94 % 10 = 4
So 17075-10-4 is a valid CAS Registry Number.

Sulfonyl halide synthesis by thiol oxyhalogenation using NBS/NCS – iPrOH

Silva-Cuevas, Carolina,Perez-Arrieta, Carlos,Polindara-García, Luis A.,Lujan-Montelongo, J. Armando

supporting information, p. 2244 - 2247 (2017/05/16)

A rapid and facile method provides a general route to sulfonyl bromides/chlorides by the oxidation of thiols using NXS – ROH (X?=?Br,Cl, R?=?iPr) as an oxyhalogenation reagent. Control experiments suggest that the alcohol component is the source of oxygen. The proposed method enable the access to structurally diverse sulfonyl bromides and chlorides including challenging examples, inaccessible by other synthetic methods.

The thermal desulfination of allylic sulfonyl halides

King, Malcolm D.,Sue, Rodney E.,White, Rodney H.,Young, David J.

, p. 4493 - 4496 (2007/10/03)

Allylic sulfonyl halides can be generated by halogenolysis of the corresponding triorganotin sulfinates. Allylic sulfonyl bromides and iodides undergo a first order, thermal desulfination with allylic rearrangement to yield the corresponding allylic halides. The desulfination of a cyclic allylic sulfonyl bromide is stereospecific, proceeding with γ-syn bromine migration.
