Oxidative Cyclization of Sulfamate Esters Using NaOCl

01 01 2009Oxidation of 3-heteroaryl-substituted sulfamates affords surprisingly disparate results with the pyrazole adduct proving to be one of the top performing substrates (entry 2) By contrast the indole-based sulfamate gives only trace product returning mostly starting material instead (entry 3) The same substrate when treated with a Rh-tetracarboxylate catalyst and PhI(OAc)

A comparison of methods for total sulphur analysis of tree

Three methods were compared for total sulphur analysis of tree foliage: magnesium nitrate ashing followed by turbidimetry sodium hypobromite (NaOBr) oxidation followed by colorimetry and an instrumental method using the Fisher S analyser model 475 The latter method was found to be substantially better than the other methods with respect to accuracy and speed of analysis and of

seeking answer to question about the element bromine

17 07 2009To solve oxidation questions you must calculate the oxidation states of each of the elements within the compound while maintaining their positive or negative charge From here you move the calculated charges to the other side of the compound like a mathematical equation and change their signs accordingly Then solve mathematically for the oxidation state of the chosen element I will

Rules for Assigning Oxidation Numbers

The oxidation number of a Group VIIA element in a compound is -1 except when that element is combined with one having a higher electronegativity The oxidation number of Cl is -1 in HCl but the oxidation number of Cl is +1 in HOCl The sum of the oxidation numbers of all of the atoms in a neutral compound is 0 The sum of the oxidation numbers in a polyatomic ion is equal to the charge of

In other words the oxidation ability of NaOCl is twice larger than that of NaOBr but the rate of substitution by HOBr is 17 times higher than by HOCl Accordingly it can be assumed that humic acid is first oxidized by OCl − to give monohalogenated carbanion(I) and the resultant carbanion is substituted by HOBr faster than by HOCl to dihalogenated carbanion (II) as follows: Humic acid
