摘要
Cpds. of formula (I): (where R1 is 1-4C alkyl; R2 is Me or Et; R3-R6 are H, Cl or Br; R7 is H, Cl or NO2) are pref. prepd. by (a) reacting the corresp. 2-hydroxydiphenyl ether (or its salt) with R2O (R1S)POCl; (b) reacting the corresp. 2-(R2O)(Cl)P(O)O-substd. cpd. with R1SH (or its salt); or (c) reacting the corresp. 2-(R1O)2P(S)O-substd. cpd. with (R')3N, R'OCSSM, MSR' or MS followed by R2Hal (where R' is alkyl; M is alkali metal, NH4 or alkylammonium; Hal is halogen).
