Triethyl phosphite → Fosarilate

Participants

Reaction Steps

A mixture of 10 g (0.0313 mole) of 6-(2-chloro-4-methoxyphenoxy)hexyl bromide and 5.2 g (0.313 mole) of triethyl phosphite was heated at 180°-190° C. for two hours. The reaction mixture was distilled in vacuo, and the fraction (4.6 g) collected at 183°-185° C. (0.03 mm) was redistilled to give 3.6 g of diethyl [6-(2-chloro-4-methoxyphenoxy)hexyl]phosphonate, b.p. 195°-197° C. (0.005 mm).
