Popis: It was established that 2,5-dibromo-3-R-4-arylthiophenes form organodimagnesium compounds in ether with the “accompaniment” of dibromoethane. It is shown that because of steric hindrance, only 2-ethoxalyl-3-R-4-arylthiophenes are formed in the reaction of the organodimagnesium compounds with diethyl oxalate. It was established that the bromomagnesiumethoxycarbinolates obtained from the indicated thiophenes and bromomagnesium ethoxide have high thermal stabilities. The IR and PMR Spectra of the synthesized compounds were studied.
