摘要 Reaction of simple dialkyl phosphites with symmetrical 1,3,5-trisubstituted hexahydro- triazines (HHTs) in the presence of benzyl chloride, afforded tertiaryaminomethylphosphonates in excellent yields. Glyphosate, a-aminomethylphosphonates and their derivatives can therefore be synthesized by this procedure conveniently.

Glyphosate, a-aminomethylphosphonates and their derivatives can therefore be synthesized by this procedure conveniently.
