Coutrot, P. published the artcileDiethyl (chloromagnesio)methanephosphonate. A novel Grignard reagent and its use in organic synthesis, HPLC of Formula: 66197-72-6, the publication is Journal of Organometallic Chemistry (1986), 316(1-2), 13-18, database is CAplus.
(EtO)2P(O)CH2MgCl (I) was obtained by an exchange reaction between (EtO)2P(O)CH2I and Me2CHMgCl in THF at -70°. Reactions of I with electrophiles are described, and compared with those of the analogous lithium or copper derivatives E.g. I reacted with PhCHO to give (EtO)2P(O)CH2CH(OH)Ph. I is especially reactive towards phenylselenium halides and halogens.
