SYNTHESIS OF ORGANIC DEUTERIUM COMPOUNDS: III. 1,2-DIBROMOETHANE-d4 AND ITS DERIVATIVES

Abstract

Acetylene and hydrogen bromide react thermally without catalysts as well as photochemically to give high yields of 1,2-dibromoethane. The preparation of the following compounds containing 99 + % deuterium is described: acetylene-d₂, 1,2-dibromoethane-d₄, 1,2-dibromoethane-1,2-d₂, ethylene-d₄, 1,2-dichloro-ethane-d₄, and ethylene-d₄ oxide. The vapor pressure of ethylene-d₄ oxide was determined in the temperature range −42 to 0 °C.
