In the presence of samarium iodide α-halophosphonates react with aliphatic carbonylcompounds (aldehydes and ketones) to afford β-hydroxyphosphonates in fairly good yields under neutral and mild conditions. Lower yields are obtained with aromatic carbonylcompounds.

Low-valent cobalt complexes were used in Reformatsky-type additions of alpha-halophosphonates to carbonyl compounds (ketones and aldehydes) to yield a variety of beta-hydroxyphosphonates. (C) 1998 Published by Elsevier Science Ltd. All rights reserved.

A substoichiometric protocol for Reformatsky-type addition of alpha-haloesters, alpha-haloketones, alpha-halonitriles, and alpha-halophosphonates to carbonyl compounds has been developed. beta-Hydroxyesters and beta-hydroxynitriles were obtained in good to excellent yields.
