Padwal | | Publisher : | | | Ashok Yakkaldevi | | Article Series No. : | | | ROR-1943 | | Article : | |  | Author Profile | | Abstract : | | | The kinctics of formation of benzothiazolcs by carrying cyclacondensation of aryl thioureas using molecular bromine as reagent in chloroform has been investigated. The order of reaction, thcrmodynamic parameters, probable mechanism and rate expression arc reported.
The kinctics of formation of 2-amino-O-substituted benzothiazolcs has been investigated. The cyclocondensation of arylthioureas in the presence of bromine in chloroform medium was found to yield the title 2-aminobenzothiazoles. The Older of the condensation was found to be second order i,e. first order with respect to thioureas and first order with respect to bromine. The effects of substituents on the rate of the condensation have also been investigated.
