    摘要: The reaction of amino acids and a haloalkylphosphonic acid to form the corresponding phosphonoalkylated amino acid is promoted by use of a catalytically effective amount of a polyamine catalyst which contains a sufficiently high concentration of amine nitrogen atoms to promote the reaction.

    摘要: Copolycondensation products of .beta.-haloalkyl phosphates and dialkyl phosphonates are useful fire retardant agents. The products are prepared by heating the starting materials at a temperature of about 110.degree. to 250.degree. C., preferably in the presence of a nucleophilic catalyst, until at least one mole of alkyl halide per mole of phosphonate is driven off. Preferred are copolycondensation products obtained by substantially complete removal of halogen as alkyl halide.

    摘要: Compounds having excellant insecticidal properties and utility as fire retardants have the formula: ##EQU1## wherein X is halogen, the R substituents can be hydrogen, hydrocarbon or substituted hydrocarbon radicals, and the R.sub.7 and R.sub.8 can additionally be halogen. Halogenation products of the foregoing compounds are especially useful.
