Abstract
A very convenient reaction of trialkyl phosphites with aldehydes or ketones in the presence of hydrogen chloride gives dialkyl 1-hydroxyalkylphosphonates in good yields via an Arbusov-like reaction of oxonium salts derived from aldehydes or ketones. This reaction is an alternative to the well-known Abramov reaction.
