The metallation of alkyl bis-(dialkyloxyphosphonyl-methyl)-phosphinates (I) and tris-(dialkyloxyphosphonyl-methyl)-phosphine oxides (II) proceeds quantitatively with Na, K, or NaH in inert organic solvents. Alkylation of these metallated derivatives is effected with alkyl halides. In addition to the mono-alkylated products, the di-alkylated and the non-alkylated products are formed also.
