Abstract
1. By the reaction of ethyl(2,2,2-trichloro-1-hydroxyethyl)phosphinic esters with acetic anhydride in presence of a few drops of sulfuric acid (1-acetoxy-2,2,2-trichloroethyl)ethylphosphinic esters were obtained. 2. By the reaction of alkyl hydrogen ethylphosphonites with chloral ethyl(2,2,2-trichloro-1-hydroxyethyl)-phosphinic esters were obtained. 3. In the dehydrochlorination of ethyl(2,2,2-trichloro-1-hydroxyethyl)phosphinic esters rearrangement occurs with formation of alkyl 2,2-dichlorovinyl ethylphosphonates.
