摘要

Prepn. of phosphono cpds. (I) of formula (A) (R1O)(R2O)P(=O)Z (A) where Z = CH(X)-CH2-Y, comprises reacting a phosphite (II) of formula A where Z = H, with an ethylenically unsatd. cpd. of formula (III) X-CH=CH-Y (III) in the presence of both a basic catalyst of formula (IV) MOR3 (IV) and a divalent metal halide or (hydr)oxide, where in all these formulae R1, R2 = 1-4C alkyl or phenyl, opt. with Cl or Br substit(s).; X = H or Me; Y = -COOR1, -CONH2, -CONHR1, -CONR12 or -C=N; M = an alkali metal, pref. Na or K; R3 = as R1, pref. unsubstd. alkyl, esp. Me or Et.
