2,3-Dichloropropene, dehalogenation

Freshly distilled allene should be used. It should be free of 2-chloropropene, usually present in allene prepared by zinc dehalogenation of 2,3-dichloropropene,3 to avoid formation of chlorine-containing products that liberate hydrogen chloride on distillation. 

The degradation of 2- and 3-chloroacrylate displays novel features. The degradation of 2-chloro-acrylate by Burkholderia sp. strain WS is initiated by a 2-haloacrylate reductase with the formation of (5)-2-chloropropionate that undergoes dehalogenation to (J )-lactate (Kurata et al. 2005). The degradation of 1,3-dichloropropene by Pseudomonas pavonaceae (cichorii) strain 170 involves a series of steps by which tra 5 -3-chloroacrylate is formed (Poelarends et al. 1998). This was degraded...
