Several alkyl hydrogen methylphosphonates of structure RO(HO)P(O)Me were synthesised by a three-stage route [R = i-Pr, n-Bu, i-Bu, s-Bu, pinacolyl Me3C-CH(Me)-, cyclopentyl and cyclohexyl]. Trimethyl phosphite was transesterified with alcohols in the presence of sodium catalyst to give the mixed phosphites (MeO)2POR in 6–64% yield. Treatment of these with methyl iodide gave alkyl methyl methylphosphonates
