2-Chloroethylphosphonic dichloride

The synthesis and characterization of VPA was previously described by Kabachnik and Medvedev. They used vinylphosphonic dichloride as the starting reagent, which was prepared by catalytic dehydrochlorination of the already known 2-chloroethylphosphonic dichloride (Scheme 4.1) by passing its vapor through a quartz tube filled with barium chloride at high temperature. ... 

Chloroethylphosphonic dichloride added to a stirred mixture of anhydrous benzyl alcohol, tetradecanol, and pyridine in benzene at 20° under N2, and stirring continued for 24 h - benzyl tetradecyl 2-chloroethylphosphonate (Y 40%), in acetic acid...
