The reaction of trialkyl phosphites with aldehydes or ketones in the presence of hydrogen
chloride gives dialkyl 1-hydroxyalkylphosphonates via Arbusov-like reaction of oxonium
salts derived from aldehydes or ketones. This reaction is a very convenient instant
method for the preparation of dialkyl 1-hydroxyalkylphosphonates with a good yield
as an alternative to the well-known Abramov reaction.
Abramov reaction - nucleophilic addition - addition reactions - 1-hydroxyphosphonates
