116435-51-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 116435-51-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,6,4,3 and 5 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 116435-51:
(8*1)+(7*1)+(6*6)+(5*4)+(4*3)+(3*5)+(2*5)+(1*1)=109
109 % 10 = 9
So 116435-51-9 is a valid CAS Registry Number.

Highly efficient oxidative bromination of alkanes with the HBr-H 2O2 system in the presence of catalyst

Li, Yujin,Ju, Jie,Jia, Jianhong,Sheng, Weijian,Han, Liang,Gao, Jianrong

experimental part, p. 2428 - 2432 (2011/10/03)

Various cycloalkanes and straight-chain alkanes were efficiently brominated with an aqueous HBr-H2O2 system. This oxidative brominating process was promoted by catalysis and irradiation with light. The cycloalkanes were converted to the corresponding bromo-cycloalkanes in moderate yields and the straight-chain alkanes produced dominantly secondary bromides. This simple but effective bromination method of alkanes is characterized by high atom efficiency, inexpensive reagents and the absence of organic waste, which make it a good alternative to the existing method for Ci£H activation through bromination. A simple, effective, environmentally friendly method was researched for bromination of alkanes in good yield with HBr as the origin of bromine.

Direct bromination and iodination of non-activated alkanes by hypohalite reagents

Montoro, Raul,Wirth, Thomas

, p. 1473 - 1478 (2007/10/03)

The direct functionalisation of alkanes through bromination and iodination has been successfully achieved. The combination of stoichiometric mixtures of elemental halogen and sodium alkoxides leads to the formation of alkyl hypobromites and hypoiodites as reagents. The halogenation occurs without external photostimulation under thermal reaction conditions. Georg Thieme Verlag Stuttgart.

ANOMALOUS ORIENTATION EFFECTS DURING BENZOYLOXYLATIONS BY "SILVER BROMIDE DIBENZOATE"

Bryce-Smith, Derek,Isaacs, Neil S.,Tumi, Seddeg O.

, p. 1471 - 1472 (2007/10/02)

The solid complex formed from bromine and silver benzoate reacts with both arenes and alkenes to form aryl and alkyl benzoates, respectively.Highly unusual substituent effects are observed in the benzoyloxylations of arenes.Electron-withdrawing groups (e.g. -NO2, -CN,-CO-) on the aromatic ring facilitate reaction though directing the attacking reagent exclusively to the meta position.In alkanes, tertiary positions are most prone to attack.
