Abstract
The study of the thermal stability of halogen-magnesium alkoxy-carbinolates was continued. The data obtained led to the development of procedures for the synthesis of esters of α-oxo and of α-hydroxy-acids containing the thienyl radical. An intramolecular hydrogen bond between the sulfur atom and the hydrogen of the hydroxyl group in esters of (5-bromothienyl-2)glycolic acid was revealed. The presence of this bond was confirmed by infrared spectroscopic data and by the results of the investigation of the esters of (thienyl-3)- and (4-bromothienyl-3)glycolic acids.
