Diethyl 2-chloroethyl phosphate

The 2-chloroethyl group, which is often an effective toxo-phore, was then attached to phosphorus through oxygen. No reaction appeared to take place between ethylene chlorohydrin and diethyl phosphorochloridate in the absence of a tertiary base. In the presence of pyridine, however, which removed the hydrogen chloride formed, a smooth reaction took place at 0° with the formation of diethyl 2-chloroethyl phosphate,... 

USGS researchers found that at least one of these chemicals was present in more than 80 percent of the rivers and streams examined. Half of the streams had seven or more of the chemicals, and about a third contained 10 or more. The most common substances encountered were coprostanol (a fecal steroid), cholesterol, N,N-diethyl-toluamide (an insect repellent), caffeine, triclosan (a disinfectant), tri(2-chloroethyl) phosphate (a fire retardant), and 4-nonylphenol (a product of the degradation of detergents). None of the chemicals found occurred in very high concentrations. For the less common chemicals, concentrations sometimes ranged as low as less than 1...

The Perkow reaction of triethyl phosphite with 2-chloroethyl trichloroacetate gives 0,0-diethyl-0-[l-(chloroethoxy)-2,2-dichlorovinyl] phosphate (69), introduced under the trade name Forstenon (Sallmann, 1952).
